Subject: [PATCH 00/13] MIPS: move pic32.h header file from asm to
 platform_data

There are currently some pic32 MIPS drivers that are in tree, and are
only configured to be compiled on the MIPS pic32 platform. There's a
risk of breaking some of these drivers when migrating drivers away from
legacy APIs. It happened to me with a pic32 clk driver.

Let's go ahead and move the pic32.h from the asm to the platform_data
include directory in the tree. This will make it easier, and cleaner to
enable COMPILE_TEST for some of these pic32 drivers.

I included a patch at the end that shows enabling COMPILE_TEST for a
pic32 clk driver.

Merge Strategy
==============
- Patches 1-12 can go through the MIPS tree.
- Patch 13 I can repost to Claudiu after patches 1-12 are in Linus's
  tree after the next merge window. There is a separate patch set that
  fixes a compiler error I unintentionally introduced via the clk tree.
