drm/amdgpu: implement TMZ accessor (v3)
Implement an accessor of adev->tmz.enabled. Let not
code around access it as "if (adev->tmz.enabled)"
as the organization may change. Instead...
Recruit "bool amdgpu_is_tmz(adev)" to return
exactly this Boolean value. That is, this function
is now an accessor of an already initialized and
set adev and adev->tmz.
Add "void amdgpu_gmc_tmz_set(adev)" to check and
set adev->gmc.tmz_enabled at initialization
time. After which one uses "bool
amdgpu_is_tmz(adev)" to query whether adev
supports TMZ.
Also, remove circular header file include.
v2: Remove amdgpu_tmz.[ch] as requested.
v3: Move TMZ into GMC.
