Remove legacy wifi driver

The driver is superseded by the new driver located in the 'pc' repository. Fixes #4508.

 version of 'libc' by linking your application to 'lxip_libc' plugin in your
 'target.mk' file.

-WiFi
-####
-
-The wifi_drv component is a port of the Linux mac802.11 stack, including the
-iwlwifi driver as well as libnl and wpa_supplicant, to Genode.
-
-To start the component the following configuration snippet can be used:
-
-!<start name="wifi_drv" caps="200">
-!  <resource name="RAM" quantum="24M"/>
-!  <provides><service name="Nic"/></provides>
-!  <config>
-!    <libc stdout="/dev/null" stderr="/dev/null" rtc="/dev/rtc"/>
-!    <vfs>
-!      <dir name="dev"> <log/> <null/> <rtc/>
-!      <jitterentropy name="random"/>
-!      <jitterentropy name="urandom"/>
-!      </dir>
-!    </vfs>
-!  </config>
-!  <route>
-!    <service name="Rtc"> <any-child /> </service>
-!    <any-service> <parent/> <any-child /> </any-service>
-!  </route>
-!</start
-
-The driver will request access to the ROM module 'wifi_config' to
-connect to a network:
-
-!<wifi_config connected_scan_interval="30" scan_interval="10" rfkill="no">
-!  <network ssid="Foobar" protection="WPA2" passphrase="allyourbase"/>
-!</wifi_config>
-
-To temporarily prevent any radio activity, the 'rfkill' attribute
-can be set to 'true'.
-
-If the network is protected by, e.g., WPA/WPA2, the protection type, either
-'WPA' or 'WPA2' as well as the the passphrase have to be specified.
-The 'bssid' attribute can be used to select a specifc accesspoint within a
-network. Of all attributes only the 'ssid' attribute is mandatory, all others
-are optional and should only be used when needed.
-
-The configuration may contain more than one network. In This case the driver
-will try to select the best one it gets a response from. To prevent it
-from automatically joining the network the 'auto_connect' attribute must be
-set to 'false'; the default value is 'true'. If the 'explicit_scan' attribute
-is set, the driver will pro-actively scan for a hidden network with the given
-SSID:
-
-!<wifi_config connected_scan_interval="30" scan_interval="10">
-!  <network ssid="Zero" protection="WPA2" passphrase="allyourbase"/>
-!  <network ssid="Skynet" protection="WPA" passphrase="12345678"
-!           explicit_scan="true" auto_connect="false"/>
-!</wifi_config>
-
-By default, the driver scans for available networks only when not
-connected. This can be changed with the 'connected_scan_interval'
-attribute, which specifies the interval for connected scans in
-seconds and directly influences any roaming decision, i.e., select
-a better fit accesspoint for the configured network.
-
-Also, the driver can be switched to verbose logging during runtime
-by setting the 'verbose' or 'verbose_state' attribute to 'true'.
-
-The wifi_drv creates two distinct reports to communicate its state and
-information about the wireless infrastructure to other components. The
-first one is a list of all available accesspoints. The following examplary
-report shows its general structure:
-
-!<accesspoints>
-!  <accesspoint ssid="skynet" bssid="00:01:02:03:04:05" quality="40"/>
-!  <accesspoint ssid="foobar" bssid="01:02:03:04:05:06" quality="70" protection="WPA2"/>
-!  <accesspoint ssid="foobar" bssid="01:02:03:04:05:07" quality="10" protection="WPA2"/>
-!</accesspoints>
-
-Each accesspoint node has attributes that contain the SSID and the BSSID
-of the accesspoint as well as the link quality (signal strength). These
-attributes are mandatory. If the network is protected, the node will also
-have an attribute describing the type of protection in addition.
-
-The second report provides information about the state of the connection
-to the currently connected accesspoint:
-
-!<state>
-!  <accesspoint ssid="foobar" bssid="01:02:03:04:05:06" quality="70" freq="2418" state="connected"/>
-!</state>
-
-Valid state values are 'connected', 'disconnected', 'connecting'. Depending
-on the state, there are additional attributes that can be checked. In case
-of an authentication error, e.g. the passphrase is wrong, the 'auth_failure'
-attribute will be set to 'true'. The 'rfkilled' attribute is set to 'true'
-if a disconnect was triggered by disabling the radio activity via setting
-the 'rfkill' attribute.
-
-By subscribing to both reports and providing the required 'wifi_config' ROM
-module, a component is able control the wireless driver.
-
-Currently only WPA/WPA2 protection using a passphrase is supported and the the
-SSID is copied verbatim. At the moment, there is no way to express or escape
-non alphanumeric characters.
-
-On certain cards, e.g. Intel Wireless 6200 ABG, it may be necessary to disable
-the 11n mode. This can be achieved by setting the 'use_11n' attribute in
-the 'wifi_config' node to 'no'.
-
-The driver optionally reports the following information under the
-label "devices" if requested in the config as depicted.
-
-! <config> <report mac_address="true"/> </config>
-
-! <devices> <nic mac_address="02:00:00:00:00:01"/> </devices>
