ASoC: fsl: clarify ac97 dependency
A new randconfig build failure shows that the fsl-asoc-card module
must not be built-in when the AC97 driver is a loadable module:
sound/built-in.o: In function `fsl_asoc_card_late_probe':
:(.text+0x571d8): undefined reference to `snd_ac97_update_bits'
I couldn't come up with a nice solution, so this adds another dependency
on "X || !X", which is the Kconfig way of saying that we have an
optional dependency on something that might be a loadable module.
