Add display ID parameter to window policy wakeUp()

Supports the per-display wake by touch project, as WindowWakeUpPolicy's
wakeUp() will need to pass on a display ID to PowerManager's wakeUP().

This also fixes a bug with the original CL where the power key failed to
wake the screen. This was due to the associated display ID for a power
key event being -1. To address this, changed PhoneWindowManager's
wakeUpFromWakeKey() to supply the default display ID to wake, instead of
the display ID from the key event.
