Janusz Krzysztofik 0841cb8268 omap: McBSP: Drop unnecessary status/error bit clearing on reg_cacheretrieved register values 
The MsBSP register cache will never have any error/status flags set, since
these flags are never written to the reg_cache. So it is kind of not
necessary to clear these flags, which are actually always 0.

In other words, clearing the status/error flags are not necessary, since the
reg_cache will never got these bits set. We can just write back the
register content from the cache as it is when clearing an error condition.

Tested on Amstrad Delta.
