x86, boot: add mmio serial during compressed boot
Allows "console=uart[8250],mmio[32],0xADDR[,BAUDn8[,BASE_BAUD]]" to
be recognized during compressed boot early console setup, and during
boot console setup. Replaces defines with common serial defines. Adds
suport for mmio-based serial devices to compressed-boot early console,
and plumbs support for defining the base baud rate for UART clock
calculations (since mmio serial cards may not have the standard rate,
resulting in incorrect baud rates for mmio devices).
