ARM: shmobile: armadillo800eva: A3SP domain includes USB

Because USB Func is controlled by external IRQ mode,
it is possible to control USB under A3SP domain to reduce power.
This patch enables it.

Armadillo800eva board switchs USB Host/Func by SW1.6,
So, the device to adds into domain is selected on this patch.
