ath79: add support for Compex WPJ563

Specifications:

SoC: QCA9563
DRAM: 128MB DDR2
Flash: 16MB SPI-NOR
2 Gigabit ethernet ports
3×3 2.4GHz on-board radio
miniPCIe slot that supports 5GHz radio
PoE 24V passive or 36V-56V passive with optional IEEE 802.3af/at
USB 3.0 header

Installation:

To install, either start tftp in bin/targets/ath79/generic/ and use
the u-boot prompt over UART:

tftpboot 0x80500000 openwrt-ath79-generic-compex_wpj563-squashfs-sysupgrade.bin
erase 0x9f680000 +1
erase 0x9f030000 +$filesize
cp.b $fileaddr 0x9f030000 $filesize
boot

The cpximg file can be used with sysupgrade in the stock firmware (add
SSH key in luci for root access) or with the built-in cpximg loader.
The cpximg loader can be started either by holding the reset button
during power up or by entering the u-boot prompt and entering 'cpximg'.
Once it's running, a TFTP-server under 192.168.1.1 will accept the image
appropriate for the board revision that is etched on the board.

For example, if the board is labelled '7A02':

tftp -v -m binary 192.168.1.1 -c put openwrt-ath79-generic-compex_wpj563-squashfs-cpximg-7a02.bin

MAC addresses:

<&uboot 0x2e010>  *:71  (label)
<&uboot 0x2e018>  *:72
<&uboot 0x2e020>  *:73
<&uboot 0x2e028>  *:74

Only the first two are used (for ethernet), the WiFi modules have
separate (valid) addresses. The latter two addresses are not used.
