serial: 8250: Split base port operations from universal driver
Refactor base port operations into new file; 8250_port.c.
Legacy irq handling, RSA port support, port storage for universal
driver, driver definition, module parameters and linkage remain in
8250_core.c
The source file split and resulting modules is diagrammed below:
8250_core.c ====> 8250_core.c __
\ \
\ +-- 8250.ko (alias 8250_core)
\ 8250_pnp.c __/ (universal driver)
\
=> 8250_port.c __
\
+-- 8250_base.ko
8250_dma.c __/ (port operations)
