[ALSA] Clean up sa11xx-uda1341 driver
Modules: SA11xx UDA1341 driver,L3 drivers,UDA1341 Clean up sa11xx-uda1341 driver: - Fix buggy destructor - Remove the global variable - Move array definitions from uda1341.h - Make functions in uda1341.c static Signed-off-by: Takashi Iwai <tiwai@suse.de>hifive-unleashed-5.1
