rockchip: serial: restyle the serial_rockchip.c driver
The ns16550.c driver has the following conditions for .of_match:
CONFIG_IS_ENABLED(OF_REAL)
For Rockchip SoCs with TPL/SPL and platform data that need serial
support the serial_rockchip.c driver was made. It copies this data
and then calls ns16550_serial_probe(). With the addition of yet an other
SoC type this driver is in need for a little restyle.
Simplify struct rockchip_uart_plat and add extra SoCs with
DM_DRIVER_ALIAS(). Return -ENODEV when the ns16550.c driver
probe function is available.
