Currently when using bccmd to do any communication, the UART is always
opened at 38.4kbps. Once the CSR has been initialized to any other
speed, bccmd can no longer communicate with with the radio (unless by
resetting it through rfkill). This patch adds a -b option allowing a
user to manually set a different speed, with the default 38400 still in
place.
Usage example:
$bccmd -t BCSP -b 921600 -d /dev/ttyHS1 chiprev
