The CMA performance optimizations depend on QGKI, which
prevents them from being enabled on configurations that don't
have a notion of GKI and QGKI. Thus, remove this dependency.
This shouldn't cause any problems with the ABI surface with
respect to GKI targets as the configs still have to be enabled
explicitly anyway.

The original design was to not send anything from qrtr-mhi until
a packet was received from the remote side. This would leave
enough time for the probe function to set up the driver_date.
With the new requirement to queue a hello packet (for Linux to
Linux communication), we may see the hello packet being scheduled
and sent before we can return and set the drvdata.
The changes to address the above requirement brings in a
possibility that driver_data in mhi layer is NULL sometimes.
Check device pointer for NULL in ul callback and return if
it is NULL.
Move the setting of driver data before registering it as an
endpoint with the qrtr framework.

The code to probe the sometimes used HW revision only needs to live in
adreno.c and we don't need to store a persistent member in adreno_device.
Localize all the code and pass the HW revision into the functions that
need it.

Context aware (CA) scaling is excluisvely a pwrscale concept so move all
the probing there. This is mostly just a cut-and-paste except that the
speed_bin needs to move from Adreno to the kgsl_device so it can be
accessed from the pwrscale code.

Throughout the history of the driver the GPU platform device and the
KGSL pseudo device have been used somewhat interchangeably which is
bad. The platform device should be used whenever dealing with hardware
or kernel resources so that we can get proper cleanup during probe.
While it is still okay to use the pseudo device for log messages,
using the platform device for log messages having to do with
resources is better since you can make a more direct correlation
between the log message and the device tree entry.

Currently we use a bitmask for the power control features (SPTP, ACD, LM,
etc). Move to individual booleans for each feature instead. Booleans
are less unweidly to use and require less if () statements.
Additionally if we properly use the Adreno feature flags when setting
and/or modifying the booleans we can get rid of the feature flag checks in
the rest of the code and use the control booleans as they are intended.
And finally, move some of the target specific control features to the
target specific code. This ensures that the target specific code can
control the feature and the other targets don't accidentally specify
the wrong state through sysfs. For example, if SPTP power collapse is
only available for a5xx then the sysfs file should only ever return
false for the other targets.

Currently, there is a custom hw_isidle function defined for a6xx but the
function pointer is removed in a6xx_start for non GMU/RGMU a6xx targets
which has the effect of falling back to the generic adreno_hw_isidle
function which confused at least two of us before we figured out what
was happening.
Instead of having a generic adreno_hw_isidle function except for a6xx, add
a hw_isidle function hook for all targets and do the GMU check in the
a6xx specific function. This also has the advantage of moving a a540
specific hack into the a5xx code and removes one of two usages of the
gpucore specific busy mask and the other is in soft fault detect.
Arguably we should get rid that too but for now we can just hardcode
the mask in there and remove the busy mask from the gpucore struct.
And finally it looks like adreno_isidle isn't used as a function hook,
so remove it from the device function tables and mark it static.

a6xx added a new function hook and path for doing a GPU reset that fell
back to the default reset path for a610 but a610 purposely skipped
soft reset and the hard reset path is very similar to that used by
GMU/RGMU enabled devices except for one little bit.
Furthermore, if a610 skipped soft reset then there are no a6xx targets
that do soft reset so there is no reason to have an a6xx specific
soft reset path. And further to that, there isn't any reason to have
any a6xx specific functions (like oob) in the generic soft reset path.
Make the a6xx reset support all a6xx targets, remove unused infrastructure
from the rest of the generic code and cleanup the generic functions
to be a little bit easier to understand.
