ath79: phy-ar7200-usb: adapt old behavior of arch/mips/ath79/dev-usb.c

[ Upstream commit 6cca6fffa06b1996f9bcc280f766e8ba4fa97d45 ]

Do not put usb-phy into reset if clearing the usb-phy reset or
setting the suspend_override has failed.

Reorder (de)asserts like in arch/mips/ath79/dev-usb.c.

Add an optional reset_control "usb-phy-analog", which is needed for
ar934x SoCs like in the old mach-driver arch/mips/ath79/dev-usb.c.
