dc20 containes several FPU-dependent functions without proper FPU
kernel mode enable/disable wrappers. Add the required wrappers
for both x86 and POWER.
This enables Navi DC20 support for POWER systems.

Introduce DC_FP_START()/DC_FP_END() macros to help enable floating
point kernel mode support across various architectures.

DCN requires floating point support to operate. Add the appropriate
x86/ppc64 guards and FPU / AltiVec / VSX context switches to DCN.

Sent this a bit too early, still running through checks. Watch for a V2

Sorry for the spam -- I had thought I was signed up for this list but
apparently was not, and resent a couple times.

KFD has been verified to function on POWER systems (Talos II / Vega 64).
It should be available as a kernel configuration option on these systems.

amdgpu_fence_driver_start_ring() attempts to access
UVD instance 2 during setup, while the existing UVD
instance count only allows instances 0 and 1.
Increase AMDGPU_MAX_UVD_INSTANCES by one to avoid the
invalid array access.
