serial: fsl_lpuart: Reset prior to registration
Since commit bd5305dcabbc ("tty: serial: fsl_lpuart: do software reset
for imx7ulp and imx8qxp"), certain i.MX UARTs are reset after they've
already been registered. Register state may thus be clobbered after
user space has begun to open and access the UART.
Avoid by performing the reset prior to registration.
Fixes: bd5305dcabbc ("tty: serial: fsl_lpuart: do software reset for imx7ulp and imx8qxp")
