ALSA: hda/tas2781: Fix the symbol was not declare warning reported by kernel test...

After commit 28a09d9e42c5 ("ALSA: hda/tas2781: Create an independent lib
to save the shared parts for both SPI and I2C driver") created a separated
lib for both hda-i2c and hda-spi driver, which caused this issue.
sparse warnings: (new ones prefixed by >>)
>> sound/pci/hda/tas2781_hda_spi.c:496:25: sparse: sparse: symbol
   'tas2781_snd_ctls' was not declared. Should it be static?
>> sound/pci/hda/tas2781_hda_spi.c:505:25: sparse: sparse: symbol
   'tas2781_prof_ctl' was not declared. Should it be static?
>> sound/pci/hda/tas2781_hda_spi.c:512:25: sparse: sparse: symbol
   'tas2781_dsp_ctls' was not declared. Should it be static?
