[PATCH 1/2] mmc: sdhci-of-at91: add quirk for broken HS200

[Eugen.Hristev]

From: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx>

HS200 is not implemented in the driver, but the controller claims it
through caps.
Remove it via quirk.
Without this quirk, the mmc core will try to enable hs200, which will fail,
and the eMMC initialization will fail.
