get_num_ports returns -ENODEV, and the result is stored in int, so it
should not be unsigned. Zero ports does not seem to make sense, so
make that check consistent.

Now that we have symbol namespaces, use them in MCB to not pollute the
default namespace with MCB internals.

The current checking for failure on the number of ports fails when
-ENODEV is returned from the call to get_num_ports. Fix this by making
num_ports and loop counter i signed rather than unsigned ints. Also
add check for num_ports being less than zero to check for -ve error
returns.

There were a few straggling files under drivers/tty/ that did not have
any SPDX identifier either because they entered the tree recently, or
they somehow missed the mass-tagging of commit b24413180f56 ("License
cleanup: add SPDX GPL-2.0 license identifier to files with no license")
This commit follows the same rule as b24413180f56 ("License cleanup: add
SPDX GPL-2.0 license identifier to files with no license") where files
without any specified license in them fall under GPL-2.0 as the correct
license for the individual file. Add that identifier to these remaining
files so that we don't have to guess at the license of them in the
future.

Add support for two MEN UARTs (16z025 and 16z057) to the
8250_men_mcb driver.
The 16z025 consists of up to four ports, the 16z057 has
exactly four ports. Apart from that, all of them share the
Port settings.

This patch introduces the 8250_men_mcb driver for the MEN 16Z125
IP-Core. This is a 16550-type UART with a 60 byte FIFO.
Due to strange old hardware, every board using this IP core requires
different values for uartclk. A reasonable default is included in
addition to the support of three boards. Additional values for other
boards will be added later.
This v2 has some whitespace fixes, I screwed this up yesterday.
