[PATCH 15/20] ARM: dts: imx6*-hummingboard2: rework regulators

[Russell King <rmk+kernel-I+IVW8TIWO2tmTQ+vhA3Yw@public.gmane.org>]

From: Lucas Stach <dev-8ppwABl0HbeELgA04lAiVw@public.gmane.org>

Name the regulators according to the voltage rails they are feeding in
the schematic. The USB 2-4 regulators are fixed regulators and are always
on, as they are not a VBUS supply for a single USB host port on the i.MX6,
but supply VBUS to ports behind a USB hub and there is currently no way
to model this in mainline.
