[ARM] pxa: remove machine class specific stuffs from serial driver
The only things prevent drivers/serial/pxa.c from being generic enough are: 1. IER_UUE which can be safely replaced by UART_IER_UUE as defined in serial_reg.h for PXA 2. __PREG() and FFUART/BTUART/STUART definitions to decide the UART port name And removed the un-necessary #include of <mach/...> and <asm/...> headers.
