Dmitry Borisov aabd163d73 [CPORTLIB:PC98] Refactor serial support code (#8558) ...

CORE-17977

- Fix a bug when subsequent port detection attempts fail because of
  broken FIFO management. If FIFO logic is enabled the hardware will
  not decode the legacy 0x30 and 0x32 I/O ports.
  Therefore care should be taken when accessing these ports.

- Fix hang on boot when a serial device was not connected to the COM1 port.
  Unlike 16550, a call to `CpDoesPortExist()` for the 8251 will succeed
  even when if the user has not plug the serial port into PC-98 machine.
  (I do not know how to put the 8251 into loopback mode.)
  Fix this by checking for CTS prior to the LSR loop.

- Fix hang on boot when the chosen baud rate becomes too large due to
  `DEFAULT_DEBUG_BAUD_RATE` being set to 115200.

- Some NP21/W workarounds were being incorrectly applied,
  fix them and consolidate them into one check.

- Reuse exsisting code from the NS16550 driver to avoid code duplication.

- Rename HW definitions for better naming.
