sdhci: Add SDHCI_QUIRK_NO_MULTIBLOCK quirk
Add quirk to show the controller cannot do multi-block IO. This is mainly for the Samsung SDHCI controller that currently cannot manage to do multi-block PIO without timing out. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Pierre Ossman <pierre@ossman.eu>
