Dmitry Baryshkov 7961233688 pxa2xx-ac97: switch AC unit to correct state before probing
If AC97 unit is in partially enabled state, early request_irq can trigger
IRQ storm or even full hang up. Workaround this by forcibly switching ACLINK off
at the start of the probe.

Eric Miao 1f017a9964 [ARM] pxa: move AC97 register definitions into dedicated regs-ac97.h
The optimal change would be to move the AC97 register definitions into
the AC97 driver, unfortunately, the registers are shared between several
files. Move them into a dedicated regs-ac97.h first.

Marc Zyngier 8825e8e8d0 ALSA: Fix pxa2xx-ac97-lib.c compilation
The last ALSA merge broke pxa2xx-ac97-lib.c, as it brought back
references to cpu_is_pxa21x that Eric Miao removed in commit
0ffcbfd54ea81ca24c0749f55ca4fcf3e2bdc23e:

	[ARM] pxa: make cpu_is_pxa2* macros more consistent

This patch gets rid of those references, and only keeps cpu_is_pxa25x().
