[PATCH 09/28] ARM: tegra: apalis_t30: add missing regulators

[Marcel Ziswiler]

From: Marcel Ziswiler <marcel.ziswi...@toradex.com>

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