ath79: add support for booting QCN5502 SoC

Based on wikidevi, QCN5502 is a "Dragonfly" like QCA9561 and QCA9563.
Treating it as QCA956x seems to work.

Subject: [PATCH] ath79: add support for booting QCN550x
Based on wikidevi, QCN550x is a "Dragonfly" like QCA9561 and QCA9563.
Treating it as QCA956x seems to work.
Tested on Netgear EX7300v2 which boots successfully with
the same CPU clock as the stock firmware.
