[ALSA] mpu-401: remove MPU401_INFO_UART_ONLY flag
Since the last patch made the ENTER_UART command optional, the enter_uart option and its corresponding flag have become superfluous. The uart_enter option remains for backward compatibility but just prints a warning when used. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
