ASoC: ti: rename CONFIG_SND_SOC_DM365_VOICE_CODEC_MODULE
Kconfig generates include/generated/autoconf.h to make CONFIG options
available to the pre-processor. Symbols with the value 'm' are suffixed
with '_MODULE'
Here is a conflict; CONFIG_FOO=m results in '#define CONFIG_FOO_MODULE 1',
but CONFIG_FOO_MODULE=y also results in the same define.
Also, CONFIG options that end with '_MODULE' confuse the Kconfig/fixdep
interaction; fixdep always assumes CONFIG_FOO_MODULE comes from
CONFIG_FOO=m, so the dependency is not properly tracked for symbols
that end with '_MODULE'.
For these reasons, CONFIG options that end with '_MODULE' should be
avoided in general. (I am planning on adding a check in Kconfig.)
This is the only case in the current kernel.
The new option name was suggested by Péter Ujfalusi. [1]
