[PATCH v3 04/12] ASoC: mediatek: mt8189: Propagate reg_rw clock errors

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

mt8189_afe_enable_reg_rw_clk() currently ignores errors from clock
enable and parent operations.

Propagate these errors and clean up the clocks before returning the
error.

Fixes: dc637ffeed6c ("ASoC: mediatek: mt8189: support audio clock control")
Signed-off-by: bui duc phuc <phucduc.bui@gmail.com>

Changes in v2:
 - Update the names of the goto labels.
