msm_bam_rmnet: Fix potential memory corruption

Usage of legacy string manipulation function sprintf could lead to
memory corruption as the number of bytes to be written to the
destination is not bounded. Replace sprintf with snprintf where the
number of bytes to be written is explicitly specified.

qcom: mpm-of: fix bug in finding the pending interrupts

When APPS proc wakeup from RPM assisted PC states it reads
the vMPM status register to know the reason for wakeup and
retrigger the interrupts to handle it. Current code is not
caring about actual enabled interrupts in vMPM. Sometimes
this is causing APPS proc unnecessarily triggering the
interrupts which are not raised in the system. Fix this by
considering the enabled interrupts in vMPM before triggering
the interrupts.

msm: mpm-of: set wakeup interrupt as NO_SUSPEND

The MPM wakeup interrupt is used to wakeup the Apps processor from
a system wide low power mode when the GIC isn't operational.

The MPM interrupt is configured as a wakeup interrupt by calling into
irq_set_irq_wake().It also needs to be configured with the
IRQF_NO_SUSPEND to prevent the irq from getting disabled during
suspend_device_irqs() in the suspend path. The interrupt is not
re-enabled until after gic_suspend() is executed as a part of the
syscore_suspend() callback.

If the CPU's idle thread enters RPM assisted power collapse between
suspend_device_irqs() and syscore_suspend, the masking of the RPM wakeup
interrupt could prevent wakeup by RPM.

msm: kgsl: Wake up GPU only for touch events

Register the KGSL input event handler only for
touch input events to make sure input event handler
is called only for touch input events.
