msm: vidc: Initialize kernel space stack variables

This change initializes kernel space stack variables
that are passed between kernel space and user space
using ioctls.
Non initialization of these variables may lead to
leakage of memory values from the kernel stack to
user space.

PS2-3: Correct authorship and date.

mdss_dsi: do not power down panel when sweep2wake is enabled In order to detect touches during suspend, the panel must be powered on. When sweep2wake is enabled, change one of the panel-off-cmds in mdss_dsi_panel.c from 0x10 to 0x11.

mdss_dsi_panel: keep the panel gpio active and don't trigger a reset

This way we will suffer minimum leakage when sweep2wake is being used.
All that is kept online here is the chip controlling the panel and touch panel.
That chip is probably some pmic but either way, keeping it online will cause
minimum leakage. This is an improvement upon the original patch by flar2 which
led to massive leakage from the display regulators since all were kept online.
