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.

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.

Add asynchronous read support to the PS3 vuart driver.  This is needed to
support the PS3 system manager driver.

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().

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.

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.
