am57xevm: Set IPC/Radio related permissions to system:media
Audio no longer belongs to the 'media' process. It runs in a
separated process ('audioserver') so the LAD and IPC files (/dev/cmem,
/dev/uio0, /dev/hwspinlock) couldn't be accessed anymore because
their ownership was set to media:system.
The binderized audio service is started under the 'audioserver'
user and several groups including 'media':
service audio-hal-2-0 /vendor/bin/hw/android.hardware.audio@2.0-service
class hal
user audioserver
# media gid needed for /dev/fm (radio) and for /data/misc/media (tee)
group audio camera drmrpc inet media mediadrm net_bt net_bt_admin net_bw_acct
...
So, changing the group of the LAD and IPC files to 'media' allows
the audio service to access them again.

[comment: radio is not applicable to am57xevm hence lad_dra7xx service is
not seen in init.am57xevmboard.rc]
