Fix permissions for dp_hotplug_error_code sysfs node

Browse source 
DisplayPort kernel driver passes error code/status to hardware composer
via the dp_hotplug_error_code sysfs file. When HWC receives/consumes
the error, it will write "0" into that file to reset the error code. So
this file must be readable and writable by the HWC code running with
"system" user/group permissions.

Bug: 324953626
Test: checked that SYSFS dp_hotplug_error_code has correct permissions
