tty: serial: msm_serial: code cleanup in msm_console_setup
The change does following:
- baud, flow, bits, parity were being overwritten as they were
being reinitialized after parsing. Initialize them when they are
declared so that user provided setting are not overwritten.
- msm_set_baud_rate() is anyway called in uart_set_options when it calls
msm_set_termios(). msm_reset() is called when we change the baud rate.
Hence doing away with both of these calls.
- CR_CMD_PROTECTION_EN and CR_TX_ENABLE settings are done in msm_set_baud_rate.
So do away with this here.
