mmc: msm_sdcc: Remove unnecessary delay in interrupt context

msmsdcc_request_end when called with interrupts disabled inside an
interrupt handler adds an unnecessary 5ms delay on command timeouts,
which impacts system performance. Remove this delay.

msm: spm: set vdd directly for current cpu

In cases where a cpu is setting vdd for itself we need not
call msm_spm_smp_set_vdd through smp_call_function_single.

Without this change when CPU calls for itself when interrupts
are disabled we get following warning

msm: mdm: Ignore modem crashes during image upgrade.

When a modem image upgrade is in progress we now ignore any other
crash notifications that may come from other modems. These could
trigger an SSR and cause the upgrade to fail as well.

msm: mdm: Disable panic on external mdm boot timeout

We now have the ability to not panic when we see a external modem has
not booted up within the expected timeframe. This functionality is
required in order to debug early bootup issues on the mdm's and is
configured via a sysfs flag.

msm: mdm: change where ssr_count is decremented

In fusion targets with more than one external modem, where
the modems are restarted together, ssr_count keeps track of
how many modems are still left to be completely restarted so
that any new SSR requests would be rejected until all modems
are restarted. Ssr_count should be decremented when the SSR
module sends the SUBSYS_AFTER_POWERUP notification instead of
during the powerup callback in order to be in sync with the
state of the SSR module.

msm: mdm2: Decrease leakage before QSC power-up

Cleanup of IPC gpios for driver strength and toggle
AP2MDM_STATUS only after AP2MDM_KPD_PWR is toggled, this

powering up.

cpufreq: cpu-boost: Use interruptible wait to not affect load average

Using the function wait_event in cpu_boost puts the
process enter to 'D' state which contribute to the
high load average. This change will put the process
boost_sync in the 'S' state (interruptible sleep).
