mips: add initial support for qca956x referenced board
QCA9563 is CPU used on AP152 board :
Clock speed : 750 MHz ,
Arch : Mips 74Kc,
Eth : SGMII interface,
MIMO config : 3 * 3 450M,
2 * USB 2.0,
Signed-off-by: Rosy Song <rosysong@rosinson.com>
Changes for v2:
- coding style cleanup
- remove ununsed flash chip in defconfig
- enable automatic icache / dcache size in defconfig
Changes for v3:
- add detailed information for qca956x in commit message
Changes for v4:
- remove pre-configured network settings in ap152.h
Changes for v5:
- coding style cleanup
