MLK-24374-2 arm64: dts: imx8qm: Move USBH1 to imx8qm-ss-conn

Commit ee96e9f815d6 ("MLK-24368-1 arm64: dts: imx8qm: Add support for USBH1")
caused i.MX8DXL USB PHYs to not go into low power mode via runtime suspend.

Fix it by moving the usbh1, usbmisc2 and usbphynop2 to the specific
imx8qm-ss-conn.dtsi file.

While at it, change the usbphynop2 status as disabled.
