[RFC 0/2] Add generic FPU api similar to x86

[Anson Jacob]

This is an attempt to have generic FPU enable/disable
calls similar to x86. 
So that we can simplify gpu/drm/amd/display/dc/os_types.h

Also adds FPU correctness logic seen in x86.

Anson Jacob (2):
  ppc/fpu: Add generic FPU api similar to x86
  drm/amd/display: Use PPC FPU functions
