[PATCH v4] USB: host: Add Device tree support for ohci-exynos & ehci-s5p

[Vivek Gautam]

Reworked third patch; other two got applied to 'usb-next' branch.

Changes from v3:
1) Change the function name from s5p_ehci_setup_gpio()
to s5p_setup_vbus_gpio(). 
2) Make s5p_setup_vbus_gpio() function to return void
instead of int.
3) Return void in case of failures.
