[POWERPC] PS3: Vuart rework
PS3 vuart updates to reflect the new PS3 unified device support. - Move vuart devices to the PS3 system bus. - Replace use of ps3_vuart_port_device with ps3_system_bus_device. - Make the PS3 vuart bus driver a loadable module. - Add remove() and shutdown() routines. - Move ps3_vuart_work into ps3_vuart_port_priv.tx_list. - Remove redundant spinlock ps3_vuart_work.lock. - No longer free ps3_vuart_port_device.priv on shutdown. - Cleanup Kconfig defs. - Export symbols needed for modular port drivers. - Arrange to use port numbers found in repository. - Fix bugs in ps3_vuart_read_async() and polled reading - Cleanup handling of shared interrupt with ps3_vuart_bus_interrupt_get() and ps3_vuart_bus_interrupt_put() - Add more comments to vuart.c.
