[PATCH] ARM: imx25: provide a fixed regulator for usb phys

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

The usb phys are internal to the SoC and so it their 5V supply. With
this regulator added explicitly the following (harmless) boot messages
go away:

	usb_phy_generic usbphy:usb-phy@0: usbphy:usb-phy@0 supply vcc not found, using dummy regulator
	usb_phy_generic usbphy:usb-phy@1: usbphy:usb-phy@1 supply vcc not found, using dummy regulator

Hello,

note I'm an USB noob, so please consider carefully before applying :-)
I also put the regulator near the usbphy node instead of in alphabetic
order. Not sure what is sensible/usual here, too.

Best regards
Uwe
