This driver does not request any gpios so don't free them.
Fixes L3 bus error on multiple modprobe/rmmod of ehci_hcd
with ehci-omap in use.
Without this patch, EHCI will break on repeated insmod/rmmod
of ehci_hcd for all OMAP2+ platforms that use EHCI and
set 'phy_reset = true' in usbhs_omap_board_data.
i.e.
board-3430sdp.c: .phy_reset = true,
board-3630sdp.c: .phy_reset = true,
board-am3517crane.c: .phy_reset = true,
board-am3517evm.c: .phy_reset = true,
board-cm-t3517.c: .phy_reset = true,
board-cm-t35.c: .phy_reset = true,
board-devkit8000.c: .phy_reset = true,
board-igep0020.c: .phy_reset = true,
board-igep0020.c: .phy_reset = true,
board-omap3beagle.c: .phy_reset = true,
board-omap3evm.c: .phy_reset = true,
board-omap3pandora.c: .phy_reset = true,
board-omap3stalker.c: .phy_reset = true,
board-omap3touchbook.c: .phy_reset = true,
board-omap4panda.c: .phy_reset = false,
board-overo.c: .phy_reset = true,
board-zoom.c: .phy_reset = true,
