Subject: [PATCH 5.9 333/757] tty: serial: imx: fix link error with CONFIG_SERIAL_CORE_CONSOLE=n

From: Yang Yingliang <yangyingliang@...wei.com>

[ Upstream commit 24c796926e2f88b383a76ddc871a7cdd62484f3a ]

aarch64-linux-gnu-ld: drivers/tty/serial/imx_earlycon.o: in function `imx_uart_console_early_write':
imx_earlycon.c:(.text+0x84): undefined reference to `uart_console_write'

The driver uses the uart_console_write(), but SERIAL_CORE_CONSOLE is not
selected, so uart_console_write is not defined, then we get the error.
Fix this by selecting SERIAL_CORE_CONSOLE.
