Subject: [PATCH AUTOSEL 5.4 10/24] drm/sun4i: frontend: Fix the scaler phase on A33

From: Maxime Ripard <maxime@...no.tech>

[ Upstream commit e3190b5e9462067714d267c40d8c8c1d0463dda3 ]

The A33 has a different phase parameter in the Allwinner BSP on the
channel1 than the one currently applied. Fix this.
