[Detail] We change the nvram path to /mnt/vendor/nvdata in P. It needs add search policy for fstab copying. [Solution] allow nvram_daemon mnt_vendor_file:dir search; MTK-Commit-Id: 0695da89e80b8c635be5764c5d1ba4088c38a445 Change-Id: I7ee2bd8bc6c16ac8c904e04d1f2a00da421f551e CR-Id: ALPS03841839 Feature: NVRAM Partition
