drm: mali-dp: Fix transposed horizontal/vertical flip

Browse Source 
[ Upstream commit 7916efe5b57505080b3cebf5bdb228b4eda008ea ]

The horizontal and vertical flip flags were the wrong way around,
causing reflect-x to result in reflect-y being applied and vice-versa.
Fix them.

Fixes: ad49f8602f ("drm/arm: Add support for Mali Display Processors")
