Actually otg1/2 power domain is for usb phy, which is required
to be powered up for usb remote up(e.g usb runtime suspended),
this patch set is to split the otg1/2 power domain from hsio,
so hsio power domain can be off but otg1/2 is on for runtime
PM.

pgc_otg1/2 are independent power domain of hsio, they for usb phy,
so remove hsio power domain dependency from its node.

pgc_otg1/2 is actual the power domain of usb PHY, usb controller
is in hsio power domain, and pgc_otg1/2 is required to be powered
up to detect usb remote wakeup, so move the pgc_otg1/2 power domain
to the usb phy node.
