Subject: [PATCH] ARM: OMAP4: HWMOD: make 'ocp2scp_usb_phy_phy_48m" as the main clock

commit 92702d (ARM: OMAP4: PM: fix PM regression introduced by recent
clock cleanup) makes the 'ocp2scp_usb_phy_phy_48m' as optional
functional clock causing regression in MUSB. But this 48MHz clock is a
mandatory clock for usb phy attached to ocp2scp and hence made as the main
clock for ocp2scp.
