ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimization

Browse Source 
Previously, OLPC support for the mic extensions was only enabled in the
ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set.  This was
because the old geode GPIO code was written in a manner that assumed
CONFIG_MGEODE_LX.  With the new cs553x-gpio driver, this is no longer the
case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead
include a requirement on GPIOLIB.

We use the generic GPIO API rather than the cs553x-specific API.
