Subject: drm: mali-dp: Fix destination size handling when rotating

From: Brian Starkey <[email protected]>

[ Upstream commit edabb3c4cd2d035bc93a3d67b25a304ea6217301 ]

The destination rectangle provided by userspace in the CRTC_X/Y/W/H properties is already expressed as the dimensions after rotation. This means we shouldn't swap the width and height ourselves when a 90/270 degree rotation is requested, so remove the code doing the swap.
