mmc: sdhci-msm: add SDR104 CRC workaround enablement control
On Certain chipsets, SDR104 mode might be unstable causing CRC error on
the interface. So we need a workaround which would skip printing register
dumps on CRC errors and also downgrade bus speed mode to SDR50/DDR50 in
case of continuous CRC errors. This patch adds "qcom,sdr104-wa" property
to enable this workaround if required.
