Subject: [PATCH 4/5] ARM: OMAP: Wakeupgen: AM43xx HS devices should save context like non-HS

Unlike some previous generation devices, AM43xx HS IRQ and Wakegen
context is handled by the ROM for us, and no secure service call
is needed or supported. Non-GP AM43xx devices should take the
same path as GP.
