Subject: [PATCH v3 2/6] serial: msm: Rename UART_* defines to MSM_UART_*
Using UART_* to name defines is a bit problematic. When trying to do
unrelated cleanup which also involved tweaking header inclusion logic,
caused UART_CSR from serial_reg.h to leak into msm's namespace which is
also among msm defines. Thus, rename all UART_* ones to MSM_UART_* to
eliminate possibility of collisions.
