mmc: sdhci-esdhc-imx: widen auto-tuning window for manual tuning
Expand the auto-tuning window width from 0 to 3 for manual tuning to
account for sampling point shifts caused by temperature change. This change
is based on hardware recommendation, providing enough margin for the
auto-tuning logic to locate valid sampling points.
When config the manual tuning final sample delay, need deduct the auto
tuning window width according to the IP logic.
