serial: sirf: make the driver also support USP-based UART Universal Serial Ports (USP) can be used as PCM, UART, SPI, I2S etc. this makes the USP work as UART. the basic work flow is same with UART controller, the main difference will be offset of registers and bits. this patch makes the old sirfsoc uart driver support both sirf UART and USP-based UART by making their differences become private data.
