This adds support for ACPI 5.0 enumerated Designware UARTs.
ACPI does not deliver information about uart clk, so
delivering it with the driver_data.

Now that support for RM9000 and platforms based on it has been removed,
remove the serial driver for it as well.  It's really only been a quirk
for an almost 8250 compatible UART anyway.

We first probe the legacy serial ports and then check pnp. If there
is a non-standard configuration then this might not work, also this
change is needed so we can blacklist Winbond CIR based on PNP ID.

For this to work the 8250_pnp driver must be merged into the 8250
module.

The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.

This commit removes the MCA specific 8250 UART code.

This is V2 of the Emma Mobile 8250 platform driver.

The hardware itself has according to the data sheet
up to 64 byte FIFOs but at this point we only make
use of the 16550 compatible mode.

To support this piece of hardware the common UART
registers need to be remapped, and the access size
differences need to be handled.

The DLL and DLM registers can due to offset collision
not be remapped easily, and because of that this
driver makes use of ->dl_read() and ->dl_write()
callbacks. This in turn requires a registration
function that takes 8250-specific paramenters.

Future potential enhancements include DT support,
early platform driver console and fine grained PM.

The drivers/tty/serial dir is already getting rather busy.
Relocate the 8250 related drivers to their own subdir to
reduce the clutter.

Note that sunsu.c is not included in this move -- it is
8250-like hardware, but it does not use any of the existing
infrastructure -- and does not depend on SERIAL_8250.
