8250.c: support specifying DW APB UARTs in device platform_data
Allow the private_data field to be specified in platform_data for the standard 8250/16550 UART. This field is used by DW APB type UARTs and without this patch it's only possible to set this field when registering the port by hand. If private_data is not set then the driver will potentially oops with a NULL pointer dereference.
