Currently the serial code assumes that there is always at least one serial
port (and panics / crashes due to null pointer dereferences when there is
none).
This makes it impossible to use u-boot on boards where there is no (debug)
serial port, because e.g. all uart pins are muxed to another function.
This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which
defaults to y (preserving existing behavior), which can be set to n on
such boards to make them work.
This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing
running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial,
and is not necessary at this moment.

A few nits below.
Are you OK with me fixing the nits when I apply it or would you like to resent?
I was planning on doing a v2, but I have not found the time to do
so yet. So your offer to fix the nits sounds good. Please go ahead
and fix them.
Thanks & Regards,
Hans
