[PATCH] OMAP4: PANDA, SDP: Fix EHCI regulator supply

VUSB is a fixed level line and hence have no set_voltage
callback in regulator ops, but has apply_uV set to true.
As a result it fails to register with the regulator core.
Remove setting apply_uV.

Also, assign name to VUSB supply, without which regulator core
fails to find it and assigns the default 'dummy' regulator to
the ehci-omap device.
