Subject: drm/vc4: crtc: Make state functions public
Git-commit: bdd9647296840e0cc0261deef90184cee83a8d0e
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
We'll need the CRTC state related functions to be exported so that we can
reuse them for the TXP.
