ASoC: codecs: wcd938x: fix codec initialisation race

Make sure to resume the codec and soundwire device before trying to read
the codec variant and configure the device during component probe.

This specifically avoids interpreting (a masked and shifted) -EBUSY
errno as the variant:

wcd938x_codec audio-codec: ASoC: error at soc_component_read_no_lock on audio-codec for register: [0x000034b0] -16

when the soundwire device happens to be suspended, which in turn
prevents some headphone controls from being registered.

Fixes: 8d78602aa87a ("ASoC: codecs: wcd938x: add basic driver")
