Transfer the device-tree pxa uart handling from 8250_of to the new
8250_pxa. As a corollary, add the early console definition into
8250_pxa.
This enables to have the same uart node for the early console and the
normal uart.

Initialize the tx_loadsz parameter from passed in devicetree
tx-threshold parameter.
The tx_loadsz is calculated as the number of bytes to fill FIFO
when tx-threshold is triggered.

The 8250_of never compiled since in the Kconfig we have SERIAL_OF_PLATFORM
but in the makefile we expect to have SERIAL_8250_OF...
When the 8250_of.c is actually compiled we will have two errors:
missing linux/nwpserial.h and 8250/8250.h.
Fix those as well at the same time when enable the compilation of the
driver.

As the of-serial driver is now 8250 specific, we can move the
file to a more appropriate place in teh 8250 subdirectory and
adapt the Kconfig help text and file name.
I'm leaving the CONFIG_SERIAL_OF_PLATFORM symbol unchanged
to avoid breaking user configuration files unnecessarily.
