[PATCH 4.14 027/239] mmc: sdhci-of-at91: fix quirk2 overwrite

[Greg Kroah-Hartman]

From: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx>

commit fed23c5829ecab4ddc712d7b0046e59610ca3ba4 upstream.

The quirks2 are parsed and set (e.g. from DT) before the quirk for broken
HS200 is set in the driver.
The driver needs to enable just this flag, not rewrite the whole quirk set.

Fixes: 7871aa60ae00 ("mmc: sdhci-of-at91: add quirk for broken HS200")
