mmc: sdhci-pci: Add SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC to BYT
SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC actually causes standard-compliant behaviour by causing the flagging of the last DMA transfer descriptor as the end instead of there being an additional nop descriptor which is flagged as the end. Consequently, it is better to have the quirk. Add it for BYT. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
