Subject: [PATCH 09/31] ARM: tegra: colibri_t20: add missing regulators

From: Marcel Ziswiler <marcel.ziswiler@...adex.com>

Add missing regulators:
- reg_lan_v_bus being USB Ethernet chip vbus supply
- carrier board reg_3v3 to be used as backlight and panel power supply
- carrier board HDMI supply being reg_5v0
- reg_usbc_vbus being the USB vbus supply of the EHCI instance 0
