[U-Boot] [PATCH 1/2] OMAP4: clocks-common: prevent USB DPLL from being stuck in running state

[Roger Quadros]

If board config does not select CONFIG_USB_EHCI_OMAP (e.g. omap4_sdp4430_config)
then the USB DPLL is stuck in running state and it prevents the system from
entering OFF mode (i.e. l3init domain is kept ON).

With this patch we unconditionally configure the USB DPLL so it functions
properly even on boards not using CONFIG_USB_EHCI_OMAP
