[POWERPC] PS3: Vuart cleanups
Cleanups for the PS3 vuart driver. - Hide driver private data from external interface with new structure ps3_vuart_port_priv. - Fix masking bug in ps3_vuart_get_interrupt_status(). - Add new helper routine ps3_vuart_clear_rx_bytes() to flush rx buffer. - Add new variable probe_mutex to serialize probe and destroy routines. - Rename some symbols. - Add platform check in ps3_vuart_bus_init().
