qseecom: Add support to handle multiple app load & unload

Media server is associated with multiple apps on TZ-side.
Unloading a single app for clean up is not enought. QSEECOM
needs to handle the app load & unload of multiple apps
associated with the client. During app_load & app_unload
along with app_id, app_name should also be checked. Besides,
keymaster will not be unloaded and app search execution
during app unload is optimized.

qseecom: change the number of bytes to compare app names

keymaster app has two names with different length: "keymaster" and
"keymaste". To compare the app names correctly, the shorter name
length is choosen for memcmp in __qseecom_send_cmd.

msm: mdss: synchronize recovery handler access

The recovery handler is used in the dsi event thread, and
the recovery handler variable was configured from a different
thread.  Earlier, there is no synchronization between the two
threads accessing the recovery handler, causing kernel panics.

msm: mdss: apply BW fudge factor to all controllers when video mode present

If there is a video mode controller enabled and other
controllers non-video mode, current display driver apply
the bw fudge factor only to the controller that it is
video mode.
This change will apply the fudge factor to all the
controllers enabled if any of those it is video mode to
fix some of the underruns observed in the video interfaces.

msm: mdss: ensure retire fences are signaled during panel off

When turning off command mode panel, if retire fences are still active
and suspend sequence goes through some fences may remain active.
If fences remain active command panel off sequence would stop signaling
vsyncs and would throw off the timeline. To fix this clear the retire
timeline when turning panel off.

ARM: dts: msm: Add flash_wa regulator support for msm8226 flash

Add the DT property flash-wa-supply to flash device node and assign
pm8226_chg_chgr regulator to it. This enables the flash_wa regulator
support for the flash driver.

power: qpnp-charger: Add a regulator device to control flash led WAs

Flash led relies on SMBB to supply the 5V drive voltage. Add a regulator
device in qpnp-charger driver to support flash related workarounds in
SMBB.

While at it, add a SMBB temperature threshold workaround in the
regulator device. On certain devices SMBB/SMBBP over temperature
happened at default settings before flash module start thermal derating.
Raise the SMBB over temperature threshold when regulator enabled, and
restore to default setting when regulator disabled.

leds: leds-qpnp: provide pwm period when leds are set to LPG mode in DT

In the current design, if MPP-controlled leds or RGB leds are configured
to LPG mode in the device tree, the PWM period value is not provided.
This will result in "pwm_cfg->pwm_period_us" being assigned to zero
since no PWM period value will be read from device tree. As a result,
qpnp_pwm_init() returns error, which in turn results in failure of
qpnp_mpp_init() or qpnp_rgb_init() and finally resulting in failure of
qpnp_leds_probe().

So "qcom,pwm-us" property should be provided in DT for the above case and
the property parsing needs to be implemented in the leds-qpnp driver.
