This change migrates all the relevant files consisting of the mpq
demux driver, its plugins, including the addition of TSPPv1 HW driver.
The snapshot is taken from msm-4.14:
'commit 745112 ("Migrate mpq demux driver from kernel 4.9 to 4.14")'.
In addition, introduce a few code changes to fix warnings,
typos and other style issues.
