ARM: dts: imx7: Move hsic_phy power domain to HSIC PHY node

commit 14490afe3671b972690e83482f6dd0e02118b4d4 upstream.

Move the power domain to its actual user. This keeps the power domain
enabled even when the USB host is runtime suspended. This is necessary
to detect any downstream events, like device attach.
