The function qcom_scm_mem_protect_region_id dereferences __scm without
checking for NULL and could potentially lead to a NULL pointer exception.
This scenario can happen if the clinet calls qcom_scm_mem_protect_region_id
before qcom_scm driver is even probed. Hence, check for NULL before
dereferencing it.

Do initial CPU reservation before starting VM, to
avoid any resource contention, while booting guest
VM. Remove the reservation after a configured timeout,
which defaults to 8 seconds.

Some targets do not have GSI feature. For such targets, gsi_reg
array does not get allocated. DWC3_CONTROLLER_NOTIFY_CLEAR_DB
event from gadget driver will access this unallocated memory.
Fix this by putting a check for gsi_reg.

Currently driver is not returning any error from the error
handling path if driver fails to enable power for PHY.
This patch adds a check and returns error if the driver
actually fails to set_voltage or fails to enable a particular
regulator.

Use a6x crashdumper register memory end location to know
the crashdumper status completion. This will avoid AHB
traffic while crashdumper was active in snapshot dumping
and fixes the slave timeout issue.

To properly ensure that the vdd regulator is put in the correct
operating mode, it needs to have a call to regulator_set_load()
prior to being enabled. This is crucial for platforms where the
HS PHY is the only consumer of the regulator as it could be
inadvertently left in LPM mode and cause the PHY to not function
properly.

When stop command comes during FIFO refill, it would free custom_effect
FIFO sample memory and set the pointer to NULL, and this would cause
the NULL pointer dereference during FIFO refill. To fix this, add a
mutex lock between FIFO stop and FIFO refill sequence to avoid a race.

QUP common registers should not be accessed from SVM as that
memory is assigned to PVM. So, bypass the reading of hw version
registers and rely on PVM for the specific HW initialization done
based on different hw versions.
