mmc: sunxi: Always set signal delay to 0 for A64
Experience have shown that the using the autocalibration could severely
degrade the performances of the MMC bus.
Allwinner is using in its BSP a delay set to 0 for all the modes but HS400.
Remove the calibration code for now, and add comments to document our
findings.
