For some UART hardware registers are 32 bits wide, so we will need
base_port + reg << 2 instead. Prepare for that change and unification of
MMIO between ARM and x86.

The register indexes and bitfield masks were guarded by the UART8250 config
options, but it might be (is) necessary to use them in a driver that is
UART8250 like without actually using the 8250 driver itself. To avoid any name
collision with other drivers, also change the constant prefix from UART_ to
UART8250_.

The port for console remains to be a compile time constant.
The Kconfig option is changed to select an UART port with index
to avoid putting map of UART base addresses in Kconfigs.
With this change it is possible to have other than debug console
on different UART port.

This framework was only available in ramstage. So we had to define
console output functions separately for bootblock, romstage and SMM.
Follow-up patches will re-enable all the consoles removed here,
in a more flexible fashion, and with less lines-of-code and copy-paste.
Also the driver list is not in a well-defined order and some of the
loops could exit without visiting all drivers.
NOTE: This build has no console in ramstage.
