[PATCH v2] drm/mediatek: Fix color format MACROs in OVL

[Hsin-Te Yuan]

In commit 9f428b95ac89 ("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.

You missed Doug's R-b tag in v1:
https://lore.kernel.org/all/CAD=FV=XrrhUoB9=JuPY2erLMA7S-EREqvP5t8NNuBuUiA4rZjQ@mail.gmail.com/

Can you resend v3 with both R-b tags this time?

Thanks,
Fei
