Douglas Teles 68b9ff798a Audio card working, LD_PRELOAD fix, volume/brightness hotkey fixes ...

Audio (3-iteration DTS fix chain):
- Removed duplicate pinctrl from codec node (pin conflict)
- Fixed sound-dai to reference &rk817_codec (MFD of_node mismatch)
- Removed DAPM routing/widgets (BSP codec has no DAPM widgets)
- Added 7 missing battery BSP properties

Runtime fixes:
- unset_preload.so prevents gl4es LD_PRELOAD inheritance to subprocesses
- ES Patch 5: getShOutput() null safety for popen() failure
- Volume hotkeys: use 'DAC Playback Volume' (not enum 'Playback')
- Brightness: 5% minimum clamp, persistence across reboots
- current_volume: reads correct ALSA control
- perfmax/perfnorm: guard DMC writes with file existence check
