pp_funcs may not exist, while dpm may be enabled. This change ensures
that KFD topology will report the same as pp_dpm_sclk, as the conditions
for reporting them will be the same.

Otherwise, we may see the issue where KFD reports "100MHz" in topology
as the max speed, while DPM is working correctly.

Using a heavy-weight TLB flush once is not sufficient. Concurrent
memory accesses in the same TLB cache line can re-populate TLB entries
from stale texture cache (TC) entries while the heavy-weight TLB
flush is in progress. To fix this race condition, perform another TLB
flush after the heavy-weight one, when TC is known to be clean.

Move the workaround into the low-level TLB flushing functions. This way
they apply to amdgpu as well, and KIQ-based TLB flush only needs to
synchronize once.

So far the kfd driver implemented same routines for runtime and system
wide suspend and resume (s2idle or mem). During system wide suspend the
kfd aquires an atomic lock that prevents any more user processes to
create queues and interact with kfd driver and amd gpu. This mechanism
created problem when amdgpu device is runtime suspended with BACO
enabled. Any application that relies on kfd driver fails to load because
the driver reports a locked kfd device since gpu is runtime suspended.

However, in an ideal case, when gpu is runtime  suspended the kfd driver
should be able to:

 - auto resume amdgpu driver whenever a client requests compute service
 - prevent runtime suspend for amdgpu  while kfd is in use

This change refactors the amdgpu and amdkfd drivers to support BACO and
runtime power management.
