msm_serial_hs : Add support for 4 Mbps baud rate for BLSP UART

BLSP based UART supports maximum clock frequency of 63.16 Mhz.
With this (63.16 Mhz) clock frequency, UART can achieve baud
rate of 3.94 Mbps which is equivalent to 4 Mbps. UART hardware
is robust enough to handle this deviation to achieve baud rate
equaivalent to 4 Mbps.
