msm_serial_hs: Using new programming sequence for BAM Based UART

There are issues seen with current programming sequence implementation
for BLSP based UART with BAM, which may possibly put hardware into
different state which may effect the required UART Tx/Rx functionality.

Hence use exact programming sequence as per the hardware programming
guide for BLSP based UART with BAM for proper UART Tx/Rx functionality.
