ARM: tegra: colibri_t30: add missing regulators

Add missing regulators:
- reg_module_3v3_audio being VDDA supply of SGTL5000
- VDDD supply of SGTL5000 actually being reg_1v8_vio
- reg_lan_v_bus being USB Ethernet chip vbus supply
- carrier board HDMI supply being reg_5v0
- carrier board reg_3v3 actually being backlight and panel power supply
