ar71xx: Add kernel 4.9 support

This add support for kernel 4.9 to the ar71xx target.
It was compile tested with the generic, NAND and mikrotik subtarget.
Multiple members of the community tested it on their boards and did not
report any major problem so far.

Especially the NAND part received some changes to adapt to the new
kernel APIs. The serial driver hack used for the Arduino Yun was not
ported because the kernel changed there a lot.

+Subject: [PATCH 1/2] MIPS: ath79: add support for QCA953x SoC
+
+Note that the clock calculation looks very similar to the QCA955x, but the
+meaning of the bits CPUCLK_FROM_CPUPLL and DDRCLK_FROM_DDRPLL is reversed.
