Revert "media: renesas: vsp1: brx: Fix format propagation"
This reverts commit 937f3e6b51f1cea079be9ba642665f2bf8bcc31f.
The change to format propagation in the BRx broke configuration of the
DRM pipeline. Revert it to fix the regression.
The original commit was meant to fix a v4l2-compliance failure, with no
known userspace applications being affected beside test tools. Reverting
is the simplest option, a more comprehensive fix can be developed (and
tested more thoroughly) later.
