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.Signed-off-by: Geoff Levand

Commit 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 changed the definition
of dev_dbg in the !DEBUG case from being a #define to being a static
inline. There was code in drivers/ps3/vuart.c to do exactly that,
which fails to compile now. This fixes it by removing the redefinition,
as the redefinition is now superfluous.Signed-off-by: Paul Mackerras

Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that
we are actually running on a PS3 (pointed out by Arnd).Correct existing checks in other subsystems/drivers to return -ENODEV instead
of zero.Signed-off-by: Geert Uytterhoeven

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().Signed-off-by: Geoff Levand

Change the PS3 irq allocation routines to take an argument indicating which
cpu (processor thread) the interrupt should be serviced on.The current system configuration favors device interrupts that are serviced
on cpu0, so that is used as the default.Signed-off-by: Geoff Levand

Adds support for the PS3 virtual UART (vuart). The vuart provides a
bi-directional byte stream data link between logical partitions.This is needed for the ps3 graphics driver and the ps3 power
control support to be able to communicate with the lv1 policy
module.Signed-off-by: Geoff Levand
