ASoC: dwc: make pcm support built-in when necessary
The new PIO mode for the dwc audio driver causes a link failure
when it is built as a loadable module but the audio driver is built-in:
sound/built-in.o: In function `i2s_irq_handler':
:(.text+0x58c64): undefined reference to `dw_pcm_push_tx'
sound/built-in.o: In function `dw_i2s_probe':
:(.text+0x593dc): undefined reference to `dw_pcm_register'
We could link both into a single module, but apparently the
author intended them to be separate, so this instead changes
the Makefile to force the pcm module to be built-in if the
base module is. This is a bit hacky but not as bad as trying
to work around it in Kconfig language.
