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
0ffcbfd5:

	[ARM] pxa: make cpu_is_pxa2* macros more consistent

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