msm_serial_hs_hwreg.h: Correcting the even parity and odd parity bits

Currently parity bits are defined to be used with UART_DM_MR2
register with PARITY_MODE Bit as below :
EVEN_PARTIY = 1 and ODD_PARITY = 2
With these values, UART functionality doesn't work after enabling parity.
Hence adding correct used PARITY_MODE bits value as
EVEN_PARITY = 2 and ODD_PARITY = 1
after confirming with UART hardware programming guide.

msm: display: fb blend setting via MSMFB_METADATA_SET ioctl

ioctl, overlay blend setting will take this into account.

In some cases, display driver is called by multiple threads, this

calling display commit, the other turns off the display. In order
to serialize the operation, mutex is added to most APIs.
Only the ones for initialization won't be added.
