[PATCH v4] ALSA: hda/tas2781: Fix the ld issue reported by kernel test robot

[Shenghao Ding]

After commit 9fa6a693ad8d ("ALSA: hda/tas2781: Remove tas2781_spi_fwlib.c
and leverage SND_SOC_TAS2781_FMWLIB")created a separated lib for i2c,
However, tasdevice_remove() used for not only for I2C but for SPI being
still in that lib caused ld issue.
All errors (new ones prefixed by >>):
>> ld.lld: error: undefined symbol: tasdevice_remove
   >>> referenced by tas2781_hda.c:33 (sound/pci/hda/tas2781_hda.c:33)
   >>>               vmlinux.o:(tas2781_hda_remove)
To fix this issue, the implementation of tasdevice_remove was moved from
tas2781-comlib-i2c.c to tas2781-comlib.c.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Even though this is an ASoC patch the fixed commit is in Takashi's
tree so it needs to go via there.
