v2: Address all the checkpatch warnings


Hello PowerPC Custodians,


These are two simple patches I've been playing with as part of my learning
process. I realize that perhaps pieces of these patches should be submitted to
their respective custodians, but given their simplicity I'm thinking one of the
powerpc custodians can apply them (York perhaps) to their tree if nobody objects

I compile-tested these patches on all the mpc8xx and mpc8[356]xxx powerpc
boards/targets and I run them on one board each of the following families of
SoC(s): MPC8xx, MPC83xx and MPC85xx

Checkpatch runs with no warnings


Regards,
Shruti.
