The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.

This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.

IS_ERR() already implies unlikely(), so it can be omitted here.

Set the mnd counter based on uartclk. This fixes a problem
on 7x30 where the uartclk is 19.2Mhz rather than the usual
4.8Mhz.

Trout incorrectly reports uartclk to be running at 19.2Mhz
It is actually running at 4.8Mhz.  For trout force mnd
counter values as if uartclk was fed by tcxo/4.

The variables were unsigned so the tests did not work.

This is used by various drivers not just serial and can be extracted
as commonality

We moved this into uart_state, now move the fields out of the separate
structure and kill it off.

msm_serial_driver is registered using platform_driver_probe which takes
care for the probe function itself.  So don't pass it in the driver
struct, too.

The tty layer is now a bit more fussy about reporting the right baud rate
back. Make the msm driver match the current state of affairs.
