Subject: drm/vc4: crtc: Remove redundant pixelvalve reset
Git-commit: 6370be84d81ec717b0353cb29441db3bc19811a0
Patch-mainline: v5.10-rc1
References: jsc#SLE-15318
Since we moved the pixelvalve configuration to atomic_enable, we're now
first calling the function that resets the pixelvalve and then the one that
configures it.
However, the first thing the latter is doing is calling the reset function,
meaning that we reset twice our pixelvalve. Let's remove the first call.
