The idea is to allow us to not depend on stock QTI Bluetooth HAL, as MAC addresses fetched from NVRAM by nv_mac script will be saved as hex-encoded files. We can decode back saved files to then the Bluetooth one be set using persist property so it can be read by Bluetooth HAL. This is loosely based on similar techniques used on Mi 9 and ZenFone Max Pro M2. Signed-off-by: Albert I <kras@raphielgang.org> Change-Id: I74d07c3c3125a04962c37fe8bfcc8385d1fd3398
