sdhci: improve no card, no reset quirk
The quirk was meant to just inhibit some resets, but ended up blocking
all of them. Fortunately, this was just what was needed. Change the
comment to reflect reality.
Also, this issue has just been observed on Samsung laptops, so reduce
the number of chips the quirk affects.
