ath79: add support for Qualcomm AP143 reference boards

Specifications:

SoC:    QCA9533
DRAM:   32Mb DDR1
Flash:  8/16Mb SPI-NOR
LAN:    4x 10/100Mbps via AR8229 switch (integrated into SoC)
        on GMII
WAN:    1x 10/100Mbps via MII
WLAN:   QCA9530
USB:    1x 2.0
UART:   standard QCA UART header
JTAG:   yes
Button: 1x WPS, 1x reset
LEDs:   8x LEDs

A version with 4Mb flash is also available, but due to lack of
enough space it's not supported.

As the original flash layout does not provide enough space for
the kernel (1472k), the firmware uses OKLI and concat flash to
overcome the limitation without changing the boot address of the
bootloaders.

Installation:

1. Original bootloader

  Connect the board to ethernet
  Set up a server with an IP address of 192.168.1.10
  Make the openwrt-ath79-generic-qca_ap143-8m-squashfs-factory.bin
  available via TFTP

  tftpboot 0x80060000 openwrt-ath79-generic-qca_ap143-8m-squashfs-factory.bin
  erase 0x9f050000 +$filesize
  cp.b $fileaddr 0x9f050000 $filesize

  Reboot the board.

2. pepe2k's u-boot_mod

  Connect the board to ethernet
  Set up a server with an IP address of 192.168.1.10
  Make the openwrt-ath79-generic-qca_ap143-8m-squashfs-factory.bin
  available via TFTP, as "firmware.bin"

  run fw_upg

  Reboot the board.

For the 16M version of the board, please use
openwrt-ath79-generic-qca_ap143-16m-squashfs-factory.bin

[use fwconcatX names, drop redundant uart status, fix IMAGE_SIZE,
set up IMAGE/factory.bin without metadata]
