[SERIAL] Remove UPF_AUTOPROBE and UPF_BOOT_ONLYMCA

Browse Source 
The functionality UPF_BOOT_ONLYMCA provided has been replaced by
the 8250_mca module, which only registers MCA ports if MCA is
present.

UPF_AUTOPROBE has no functional effect - in fact, it's never
tested.  Only ibmasm set the flag.
