Subject: drm/i915/display: Add write permissions for fec support
Git-commit: d77e37063bcee42fac93a1d9fb832493a5efd4c1
Patch-mainline: v5.15-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Though there is a write option available on fec_suport
debugfs file, so far it has been registering with read
permissions only.
