[PATCH] ASoC: mmp-sspa: Fix the error handling in probe()

[Lubomir Rintel]

If we fail after pm_runtime_enable(), we fail to undo it. Same with
clk_prepare_enable(). Let's order them after all things that can fail.

Fixes: 7d98cc648253 ("ASoC: mmp-sspa: Add support for the runtime power 
management")
