serial: fsl_lpuart: Remove unused 'bd' variable
Since commit a6d7514b14a6 ("tty: serial: lpuart: add a more accurate baud
rate calculation method") the baud rate is now calculated inside the
lpuart32_serial_setbrg() function, so we no longer need to read the
UARTBAUD register inside lpuart32_set_termios().
The 'bd' variable can be simply removed.
This fixes the following build warning with W=1:
drivers/tty/serial/fsl_lpuart.c: In function 'lpuart32_set_termios':
drivers/tty/serial/fsl_lpuart.c:1652:32: warning: variable 'bd' set but not used [-Wunused-but-set-variable]
Fixes: a6d7514b14a6 ("tty: serial: lpuart: add a more accurate baud rate calculation method")
