Subject: drm/1915/fbc: Replace plane->has_fbc with a pointer to the fbc
instance

Git-commit: 02689a2055d8a78b7cd0b722a591d1acff8b1e4d
Patch-mainline: v5.17-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
With multiple fbc instances we need to find the right one for each
plane. Rather than going looking for the right instance every time
let's just replace the has_fbc boolean with a pointer that gets us
there straight away.
