[POWERPC] Xilinx: hwicap cleanup

This fixes various items pointed out during a review of the hwicap driver.
Primarily, reversed memcpy calls, re-entrancy issues, and mutex conversion
have been addressed.  There are also fixes to comments to use the kerneldoc
format, as well as some sparse annotations.
