ASoC: tlv320adc3xxx: Don't strip remove function when driver is builtin

Browse Source 
[ Upstream commit f31e0d0c2cad23e0cc48731634f85bb2d8707790 ]

Using __exit for the remove function results in the remove callback
being discarded with SND_SOC_TLV320ADC3XXX=y. When such a device gets
unbound (e.g. using sysfs or hotplug), the driver is just removed
without the cleanup being performed. This results in resource leaks. Fix
it by compiling in the remove callback unconditionally.

This also fixes a W=1 modpost warning:

	WARNING: modpost: sound/soc/codecs/snd-soc-tlv320adc3xxx: section mismatch in reference: adc3xxx_i2c_driver+0x10 (section: .data) -> adc3xxx_i2c_remove (section: .exit.text)

(which only happens with SND_SOC_TLV320ADC3XXX=m).
