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.

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.

Even if we use status = "disabled" in mem-offline node, still the
update_memory_limit() will go and update memory_limit variable and
thus the removed memory is never added to system as the
mem-offline driver is disabled. Correct this logic.

Check for the current state of sub system restart notifier when
the LOCATOR_UP notification is given to slimbus driver and do the
slimbus initialization if the current state is already set to
SERVREG_NOTIF_SERVICE_STATE_UP_V01.
This change is needed in the cases where LOCATOR_UP notification
to slimbus driver got delayed and the state of the sub system restart
notifier is already set to SERVREG_NOTIF_SERVICE_STATE_UP_V01 as
slimbus will be expecting the SERVREG_NOTIF_SERVICE_STATE_UP_V01
notification which is not going to come as the notifier state is
already changed.

Prevent system suspend from happening during slimbus initialization
process where the NGD Slimbus component gets enummerated with
ADSP slimbus component and then queries the logical addresses of
the clients connected.
This is to prevent the issue where the slimbus driver goes to
suspend due to system suspend after the enumeration phase is
done after an SSR/PDR. Driver again resumes for querying logical
addresses of clients connected assuming enumeration process is
already done whereas it has to be re-enumerated as driver got
suspened and resumed.
