drm/mediatek: Fix color format MACROs in OVL

In commit 9f428b9 ("drm/mediatek: Add new color format MACROs in
OVL"), some new color formats are defined in the MACROs to make the
switch statement more concise. That commit was intended to be a no-op
cleanup. However, there are typos in these formats MACROs, which cause
the return value to be incorrect. Fix the typos to ensure the return
value remains unchanged.
