drm/amd/amdgpu: Simplify bitfield operations in gfx v8
This patch introduces a new macro WREG32_FIELD which is used
to write to a register with a new value in a field. It's designed
to replace the pattern:
tmp = RREG32(mmFoo);
tmp &= ~REG__FIELD_MASK;
tmp |= new_value << REG__FIELD__SHIFT;
WREG32(mmFoo, tmp)
with:
WREG32_FIELD(Foo, FIELD, new_value);
Unlike WREG32_P() it understands offsets/masks and doesn't
require the caller to shift the value (or mask properly).
It's applied where suitable in the gfx_v8_0.c driver to start
with.
