ALSA: ppc: remove redundant checks in PS3 driver probe 

The check for the FW_FEATURE_PS3_LV1 firmware feature is already performed
in ps3_system_bus_init() before registering the driver. So if the probe
function is actually used, this feature is already known to be available.

The check for the match id is also superfluous; the condition is always
true because the bus' match function (ps3_system_bus_match()) only
considers this driver for devices having:
dev->match_id == snd_ps3_bus_driver_info.match_id.
