[PATCH 4.19 63/93] mmc: sdhci-of-at91: add quirk for broken HS200

[Greg Kroah-Hartman]

From: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx>

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.
