[PATCH 0/2] powerpc: wii.dts: GPIO interrupt and button support

This patchset adds the necessary bits to wii.dts to enable interrupt
support in the GPIO controller, and defines two GPIO-based buttons,
the POWER button and the EJECT button.

I will send another patchset which will implement interrupt support in
the GPIO driver (gpio-hlwd.c).

The Hollywood GPIO controller is connected to the Hollywood PIC (&PIC1)
at IRQs 10 and 11; IRQ 10 for GPIO lines that are configured for access
by the PPC, 11 for GPIO lines that are configured for access by the
ARM926.

The Wii has POWER and EJECT buttons, which are connected through
normalization logic to the GPIO controller (the length of an assertion
of these signals is always the same, regardless of how long the user
pressed the buttons).

Applied to powerpc next, thanks.
