[ALPS03878175] Remove nvram policy

Browse Source 
[Detail]
1. Since Android P, system and vendor cannot use
   on-disk files to communicate.
   Nvram is vendor_data_file, while audio-daemon is system process.
2. Actually since Android O, audio-daemon use
   AudioSystem::getParameters() to send command to audio driver who is
   the real one who touch the nvram. This is already a HIDL,
   In other words, audio-daemon does not touch nvram directly.

[Solution] Remove unnecessary policy, which may cause build break.
