rockchip: serial: Kconfig: allow ROCKCHIP_SERIAL enabled in TPL

Browse source 
The serial_rockchip.c driver converts platdata to the data structure
used in the ns16550.c file and then calls the function
ns16550_serial_probe().
When compiled with OF_REAL the serial_rockchip.c driver returns
now -ENODEV when probed and does no harm.
The config ROCKCHIP_SERIAL is currently depends on SPL_OF_PLATDATA.
Allow serial port use for both SPL and TPL by removing this
dependency and SPL_BUILD restriction.

Select this to enable a debug UART for Rockchip devices when using
CONFIG_SPL_OF_PLATDATA (i.e. a compiled-in device tree replacemenmt).
OF_PLATDATA (i.e. a compiled-in device tree replacemenmt).
This uses the ns16550 driver, converting the platdata from of-platdata
to the ns16550 format.
