bc75954cca ath79: rename DTSI for Netgear WNDR devices based on ar7161
This renames the DTSI for Netgear WNDR devices based on ar7161 to
indicate that the file is not limited to WNDR3700 models.

61307544d1 ath79: wndr3700 series: fix wifi range & throughput
This patch adds ar71xx's GPIO setup for the 2.4GHz and 5GHz antennae
demultiplexer:

| 158         /* 2.4 GHz uses the first fixed antenna group (1, 0, 1, 0) */
| 159         ap9x_pci_setup_wmac_gpio(0, (0xf << 6), (0xa << 6));
| 160
| 161         /* 5 GHz uses the second fixed antenna group (0, 1, 1, 0) */
| 162         ap9x_pci_setup_wmac_gpio(1, (0xf << 6), (0x6 << 6));

This should restore the range and throughput of the 2.4GHz radio
on all the derived wndr3700 variants and versions with the AR7161 SoC.
A special case is the 5GHz radio. The original wndr3700(v1) will
benefit from this change. However the wndr3700v2 and later revisions
were unaffected by the missing bits, as there is no demultiplexer
present in the later designs.

This patch uses gpio-hogs within the device-tree for all
wndr3700/wndr3800/wndrmac variants.

Notes:

Based on the PCB pictures, the WNDR3700(v1) really had eight
independent antennae. Four antennae for each radio and all of
those were printed on the circut board.

The WNDR3700v2 and later have just six antennae. Four of those
are printed on the circuit board and serve the 2.4GHz radio.
Whereas the remaining two are special 5GHz Rayspan Patch Antennae
which are directly connected to the 5GHz radio.

Hannu Nyman dug pretty deep and unearthed a treasure of information
regarding the history of how these values came to be in the OpenWrt
archives: <https://dev.archive.openwrt.org/ticket/6533.html>.

Mark Mentovai came across the fixed antenna group when he was looking
into the driver:

    fixed_antenna_group 1, (0, 1, 0, 1)
    fixed_antenna_group 2, (0, 1, 1, 0)
    fixed_antenna_group 3, (1, 0, 0, 1)
    fixed_antenna_group 4, (1, 0, 1, 0)

6227c8d1bf ath79: WNDR3700 v1/v2: make u-boot env partition writable
Remove read-only flag from U-boot environment partition for Netgear
WNDR3700 v1 and v2 so u-boot-envtools can modify data there.

3e19113d5d ath79: specify "firmware" partition format for WNDR3700 and v2
Specify the new "firmware" partition format for Netgear WNDR3700
and WNDR3700v2 similarly as ffd082aa did for WNDR3800, the third
device in the family.

4dc7cb792a ath79: add WNDR3700 and WNDR3700v2
Add support for WNDR3700 and WNDR3700v2.

They share most things with WNDR3800.
Only device IDs and partition structure needs to be set.

Note: WNDR3700 (v1) has no NETGEAR_HW_ID, but has
      also the NA version of the factory image.
