Stefan Kalkowski 6106e64aac base: remove include/spec/* other than ISA
This commit moves the headers residing in `repos/base/include/spec/*/drivers`
to `repos/base/include/drivers/defs` or repos/base/include/drivers/uart`
respectively. The first one contains definitions about board-specific MMIO
iand RAM addresses, or IRQ lines. While the latter contains device driver
code for UART devices. Those definitions are used by driver implementations
in `repos/base-hw`, `repos/os`, and `repos/dde-linux`, which now need to
include them more explicitely.

This work is a step in the direction of reducing 'SPEC' identifiers overall.

This directory contains the implementation of Genode's AHCI driver

Behavior
--------

The driver supports x86 32/64 bit platforms and the Exynos5 SOC. If
more than one AHCI controller is present, the first one will be used.
Each active device on each AHCI port will be represented by a Genode
block session. The server must be configured via a policy, that states
which client can access a certain device:


!<start name="ahci">
!  <binary name="ahci_drv" />
!  <resource name="RAM" quantum="10M" />
!  <provides><service name="Block" /></provides> }
!  <route>
!    <any-service> <parent /> <any-child /> </any-service>
!  </route>
!  <config atapi="no">
!    <!-- use model and serial number -->
!    <policy label_prefix="test-ahci" model="QEMU HARDDISK" serial="QM00005" />
!    <!-- use controller port number -->
!    <policy label_prefix="bench" device="1" />
!  </config>
!</start>

In the example above, a session request labeled with "test-ahci" gains access to
a device with certain model and serial numbers, while "bench" gains access to
device at port 1. ATAPI support is by default disabled and can be enabled by
setting the config attribute "atapi" to "yes".
