From: Eugen Hristev <[email protected]> commit 7871aa60ae0086fe4626abdf5ed13eeddf306c61 upstream.
HS200 is not implemented in the driver, but the controller claims it through caps. Remove it via a quirk, to make sure the mmc core do not try to enable HS200, as it causes the eMMC initialization to fail.
