When CONFIG_SERIAL_FSL_LINFLEXUART=y and CONFIG_PRINTK is not set,
one compilation error is found as below:
drivers/tty/serial/fsl_linflexuart.c: In function linflex_earlycon_putchar:
drivers/tty/serial/fsl_linflexuart.c:608:31: error: CONFIG_LOG_BUF_SHIFT
undeclared
(first use in this function); did you mean CONFIG_ISA_BUS_API?
if (earlycon_buf.len >= 1 << CONFIG_LOG_BUF_SHIFT)
^~~~~~~~~~~~~~~~~~~~
CONFIG_ISA_BUS_API
This because CONFIG_LOG_BUF_SHIFT is depended on CONFIG_PRINTK, fix this
by adding dependence for CONFIG_SERIAL_FSL_LINFLEXUART.
