serial: 8250: move of_serial code to 8250 directory
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.
