spi_mpc83xx: fix checkpatch issues

Browse source 
Checkpatch is spitting errors when seeing the rename patch, so fix the
errors prior to moving.

Following errors and warnings were fixed:

   WARNING: Use #include <linux/io.h> instead of <asm/io.h>

Following warnings were left over, since fixing them will hurt the
readability.  We'd better fix them by lowering the indentation level by
splitting mpc83xx_spi_work function into two parts.
