ASoC: codecs: rx-macro: move to individual clks from bulk
[ Upstream commit 43b647d9940454263421f9a1c756680bdf1d443c ]
Using bulk clocks and referencing them individually using array index is
not great for readers.
So move them to individual clocks handling and also remove some unnecessary
error handling in the code.
