Add PS3 system manager support and the ppc_md routines restart() and
power_off().

The system manager provides an event notification mechanism for reporting
events like thermal alert and button presses.  It also provides support to
control system shutdown and startup.

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().

Preallocate bootmem memory for the PS3 frame buffer device, which needs a
large block of physically-contiguous memory. The size of this memory block is
configurable:
  - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the
    default amount of memory (in MiB) allocated to the virtual frame buffer.
  - The early boot parameter `ps3fb=xxx' allows to override the default value.
    It will be rounded up to a multiple of 1 MiB, if needed.

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.

Various fixes for the PS3 repository code:

  - Sync signatures of function prototypes and implementations (enum vs.
    unsigned int)
  - Correct references to `regions' as `registers':
      o Correct enum ps3_region_type as enum ps3_reg_type,
      o Correct PS3_REGION_TYPE_* as PS3_REG_TYPE_*,
      o Correct ps3_repository_find_region() as ps3_repository_find_reg().
  - Correct function name in pr_debug() call
  - Minor error condition improvements.
