Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*.
Back in the day, like more than half a decade ago, we migrated a lot
of boards to printk, but we never cleaned up the existing code to be
consistent. Instead, we worked around the problem with a very messy
console.h (nowadays the mess is hidden in romstage_console.c and
early_print.h)
This patch cleans up the generic code pieces to use printk() on all
non-ROMCC boards.
Our two remaining ROMCC boards are fixed up in this commit:
bifferos/bifferboard and dmp/vortex86ex.

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.

Option DRIVERS_UART builds with support for UART hardware.
Option CONSOLE_SERIAL enables the console output for UART.
Those x86 boards that do not have serial port on SuperIO should select
NO_UART_ON_SUPERIO to disable 8250 UART for the default configuration.
Removes:
CONSOLE_SERIAL_UART

Divisor is a function of requested baudrate, platform-specific
reference clock and amount of oversampling done on the UART reference.
Calculate this parameter with divisor rounded to nearest integer.
When building without option_table or when there is no entry for
baud_rate, CONFIG_TTYS0_BAUD is used for default baudrate.
For OxPCIe use of 4 MHz for reference was arbitrary giving correct
divisor for 115200 but somewhat inaccurate for lower baudrates.
Actual hardware is 62500000 with 16 times oversampling.
FIXME: Field for baudrate in lb_tables is still incorrect.

These features depend on CAR_GLOBAL region, which is not available
when romstage is built with ROMCC. Exclude these from romstage, keep
them available for ramstage.
A follow-up patch will fix the dependencies and allows enabling these

- shift most (romcc) code out of console.h into arch/x86/lib/romcc_console.c
- rename arch/x86/lib/printk_init.c to .../romstage_console.c
- drop FUNCTIONS_FOR_PRINT since __console_tx_* are already functions, so there
should not be any side effects to eliminating another indirection.
