drm/vc4: Fix clock source for VEC PixelValve on BCM2711

Browse Source 
[ Upstream commit fc7a8abcee2225d6279ff785d33e24d70c738c6e ]

On the BCM2711 (Raspberry Pi 4), the VEC is actually connected to
output 2 of pixelvalve3.

NOTE: This contradicts the Broadcom docs, but has been empirically
tested and confirmed by Raspberry Pi firmware devs.
