Subject: [PATCH v2] tty: serial: fsl_lpuart: select SERIAL_FSL_LPUART for SERIAL_FSL_LPUART_CONSOLE

A rand config causes this link error
ld: drivers/tty/serial/earlycon.o: in function `parse_options':
drivers/tty/serial/earlycon.c:99: undefined reference to `uart_parse_earlycon'

The rand config has
CONFIG_SERIAL_CORE=m
CONFIG_SERIAL_EARLYCON=y
CONFIG_SERIAL_FSL_LPUART=m
CONFIG_SERIAL_FSL_LPUART_CONSOLE=y

SERIAL_FSL_LPUART should have been selected instead of depends on-ed.

After applying the configs are
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_EARLYCON=y
CONFIG_SERIAL_FSL_LPUART=y
CONFIG_SERIAL_FSL_LPUART_CONSOLE=y
