bluetooth: update bluetooth-power platform data

Update bluetooth power driver to support both device tree and
board specific platform data to power on bluetooth chipset.

Current driver supports only gpio data from the device node.
Now the driver first checks for device tree node and if it
does not exist then checks for the platform data from the
board file.

Updated the platform data for the driver to provide all the
required vregs and gpio data to power on the bluetooth
chipset.

msm_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.

cfg80211: unblock user hint when cfg80211_regdom is intersected

If the driver is loaded when cfg80211_regdom is intersected then
user hint will fail for the first time since cfg80211 does not
have a check to see if cfg80211_regdom is intersected. Add
a check to see if cf80211_regdom is intersected and allow the
user hint to be processed.

msm_fb: display: reference count base pipe free in dsi and lcdc

During dsi off or lcdc off, base pipe could be freeed if fb device is
closed. Since base pipe allocation and free are managed through
reference counting api functions, so those free functions api should
be called.

media: dvb: check filter is valid for fullness callback

In PULL mode, all relevant filters' buffer space is checked
to ensure sufficient space or otherwise blocking untill it
becomes available. As callback might sleep it is called without
holding any locks. So at this time, just before the callback executes,
the filter might have been closed by a different thread.
To prevent invalid access, verify in the callback that filter is still
valid.

msm_fb: display: turn off lcdc timing generator when splash is done

The lcdc timing generator is configured by boot loader for splash
screen. TG should be disabled when kernel is about to configure it
with its own parameters. Otherwise, mdp may hang or underrun while TG
is still active.

msm_fb: display: fix pipe solid fill initialization issue

Currently solid fill mode is not properly initialized. Only the base
pipe allocated for the interface is supposed to be initialized before
interface timing generator is turned on. However, the solidfill_init
function initializes all pipes and this could cause underruns on the
pipes already being used.
