Subject: [PATCH 03/21] ARM: ux500: Clean-up MSP platform code

This patch contains a couple of general MSP clean-ups and a bug-fix.
The general clean-ups pertain to layout changes and changing functions
to be void instead of int and not to regardlessly return '0'. The bug
that's fixed is thought to be caused by a merge error. The code
erroneously attempts to platform_device_register a non-existent struct.
It's a simple fix, just reference the correct platform_data structure
in its place.
