serial: T8853: limit "kernel" CLI option to ttyS and ttyAMA interfaces only (#5193)
Recently (commit 35db941bcf "serial: T8375: add CLI option to explicitly set
kernel console") we added the CLI knob to enable the Kernel and GRUB serial
console on a given device.
Currently this is supported for serial console interfaces starting with ttyS
and ttyAMA only. Main limitation is that these interfaces are wired to the CPU
and bootloader infos can be displayed.
