patch for persistent bluetooth mac address

[well0nez]

it creates the directory
/data/misc/bluetooth/

in the rootfs and comments out
#define USE_MAC_FROM_RDA_NVRAM
in hci_core.c

we can observe, that the persistence of the bt mac address has written into function which depends on CONFIG_BT_RANDADDR
which is likely odd, very bad programming here.

Ahh yes, I guess this is hardly surprising since the wireless is exactly the same. Thanks for following how the wireless fixes worked. That will make it much less confusing that everything is stored in that same place.

Thanks a ton for the further fixes, everything looks good!
