console: serial: add optional delay to wait for BMC serial routing

Some mainboards with a BMC do the serial routing setup in the BMC boot
phase on cold boot. This results in scrambled console output when this
is not finished fast enough.

This adds a Kconfig-based delay that can be set at mainboard level to
wait for the BMC to finish setup.

A user may set this delay to 0 when using another BMC firmware like
OpenBMC, u-bmc or some custom BMC bootloader with fast serial setup.
