drm/vc4: crtc: Drop feed_txp from state
Accessing the crtc->state pointer from outside the modesetting context is not allowed. We thus need to copy whatever we need from the KMS state to our structure in order to access it. In VC4, a number of users of that pointers have crept in over the years, the first one being whether or not the downstream controller of the pixelvalve is our writeback controller. Fortunately for us, Since commit 39fcb2808376 ("drm/vc4: txp: Turn the TXP into a CRTC of its own") this is no longer something that can change from one commit to the other and is hardcoded. Let's set this flag in struct vc4_crtc if we happen to be the TXP, and drop the flag from our private state structure.
