ARM: dts: imx6sl: add phy-3p0-supply to usb phys

Browse Source 
The integrated usb phys are supplied by the 3p0 regulator, which has a
voltage range of 2.625V to 3.4V. Thus the min and max values are
corrected and the regulator added as a proper supply for the usb phys.

This fixes the following warnings during the probe of the mxs_phy
driver:

mxs_phy 20c9000.usbphy: supply phy-3p0 not found, using dummy regulator
mxs_phy 20ca000.usbphy: supply phy-3p0 not found, using dummy regulator

The 3p0 regulator handling was introduced by commit 966d73152078 ("usb:
phy: mxs: enable regulator phy-3p0 to improve signal qualilty")`.
