Subject: [PATCH] ath79: ag71xx: fix pll-data setting for
 ar7242/ar934x/qca955x/qca956x

ar71xx/ar913x series use the old pll registers and settings.

However started from ar7242, a new pll register is introduced and the
pll setting is much simpler.

This can be observed from dev-eth.c from the ar71xx target.
