If needed, the IOMMU device can define a CX GDSC to enable before
turning on clocks to directly write IOMMU registers.

Move ownership of the IOMMU clocks to the KGSL device and get them from
there during IOMMU probe. This ensures that the clocks are owned by a
proper platform device that can sync_state() after we are done probing.

Traditionally the GMU/RGMU device has been a child of the adreno device
and probed manually. That has worked despite the fact that the GMU/RGMU
device has resources of its own and it really should be a top level
platform device.
Finally do the right thing, make GMU a top level platform device and
driver and bind it to Adreno as a component. This will make sure we
get the advantages of all of the platform level initialization without
having to code in half a dozen hacks to make everything work and then
break again next kernel version.

The KGSL bus probe was not quite resilient for a deferred probe. Move
a memory allocation to devm and make sure that the interconnect handle
is properly put away on failure.

Update the frequencies of the clocks from Hz to KHz so that they
match the frequencies requested by the DisplayPort driver. This
ensures that the clock framework correctly scales parent clock
values for all DisplayPort clock requests.

qsmmuv500_iova_to_phys_hard() takes in the IOMMU domain as an
input parameter, but only uses it to derive the SMMU domain.
In preparation for moving this function out to a file where
to_smmu_domain() will not be available, require that the input
argument be an SMMU domain, instead of the IOMMU domain. This
change has no functional impact.

DOMAIN_ATTR_DEBUG is queried by the qsmmuv500_iova_to_phys()
function, which will move outside of arm-smmu.c, requiring
arm_smmu_domain_get_attr() to be exposed, which doesn't make
sense for only one attribute.
Thus, remove this domain attribute and inform the SMMU driver
that it is operating on a debug domain by introducing a new
marker in the msm_iommu_domain for debug domains. This patch
has no functional impact.

arm_smmu_init() has retained some workarounds for
back when it could be invoked multiple times as either
part of the initcall sequences, or through the IOMMU
OF table. This was necessary before the driver
core handled dependencies between an IOMMU master
and an IOMMU device. Since this is no longer the case,
we can remove this logic. Also, while we're here,
unregister the TBU driver if the SMMU driver cannot
be registered.
