[ Upstream commit 6d020d81b91af80a977061e82de25cafa4456af5 ]
Given that only the MM21 capture format is supported by userspace tools (like gstreamer and libyuv), make it the default capture format.
This allows us to force the MM21 format even when a MM21 and MT21C capable firmware is available (which is needed while dynamic format switching isn't implemented in the driver), without causing the following regressions on v4l2-compliance:
fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_G_FMT: FAIL fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_TRY_FMT: FAIL fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_S_FMT: FAIL
