superio/aspeed/common: add workaround for serial routing delay quirk
Some mainboards with an ASPEED 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 delay of 500ms as workaround in the BMCs uart setup that
can be selected at mainboard level.
A user may disable the workaround when using another BMC firmware like
OpenBMC, u-bmc or some custom BMC bootloader with fast serial setup.
