[PATCH 5.11 023/601] ASoC: tlv320aic32x4: Register clocks before registering component

From: Annaliese McDermond <nh6z@nh6z.net>

commit 1ca1156cfd69530e6b7cb99943baf90c8bd871a5 upstream.

Clock registration must be performed before the component is
registered. aic32x4_component_probe attempts to get all the
clocks right off the bat. If the component is registered before
the clocks there is a race condition where the clocks may not
be registered by the time aic32x4_componet_probe actually runs.
