codinaxxx: Update audio defines
codinaxxx: Add audio header
sepolicy: specifiy system block device.

-fixes remount /system issues.
recovery: fix usb init and isolate recovery.

-This fixes USB issues in recovery.

-This also pulls the j4fs and param modules and puts them
in the initramfs of recovery to maintian a vermagic match
with the recovery kernel. The modules are loaded from initramfs
before system is mounted.

NOTE: Initramfs path /system/lib/modules is hidded after /system
is mounted.
fix: usb

-From here https://github.com/Team-Exhibit/android_device_samsung_codinaxxx/commit/4d73cfba22fc6670f41cae0bc34f393ccd11da93
partial revert: "recovery: fix usb init and isolate recovery."

-This method of isolating recovery will not work in the build
environmet because "there is no rule to make j4fs.ko and param.ko"
because product file coping happens at the begining of the build.

NOTE: It would work on a dirty build but not a clean one.
init: restore stock usb initialization.
