msm: Adding mechanism to Stop CAMIF Immediately

Currently we have the mechanism to stop CAMIF immeidately from
Kernel Space. This change provides access to this mechanism.

Improving the procedure for CAMIF Stop:
Implemented the recommended mechanism for CAMIF Stop.

This changes improves latency to meet 100ms requirement for
flush() call.

power: max17048: power down if the battery voltage is too low

The battery could be not charged depends on system load even
if the charger is plugged. Since application doesn't power
down the device when the charger is plugged even if battery
level reach to 0%. As a result, the battery could be severely
drained under this condition.
To avoid sudden power loss by UVLO, monitor the battery voltage
and power down the device if the battery voltage drop below the
threshold.

mm: panic on the first bad page table entry access

Sometimes having a number of bad page table entries precipitates in
a crash much later. Because of this, we do not have any context for
the point at which the first bad pte entry was encountered. Hence,
panic on first such instance to help gather context for debug.

spi_qsd: set device's runtime PM status to 'suspended'

Sometimes system suspend is initiated before runtime
PM's auto-suspend delay expires and causing devices to
not suspended runtime. As part of system suspend if
device is not suspended runtime then clocks and gpios
are manages by system suspend.

If spi client does initiate transaction request immediately
after system resume then spi doesn't resume run-time
immediately as spi controller's device state is not in
'suspended state'.

Keep device's runtime PM status to suspended during
system suspend.
