A64 supports automatic delay calibration and Linux driver uses it instead of hardcoded delays. Add support for it to u-boot driver.
So technically that should be derived from the node's compatible string, like we do in Linux. But I see that we are not there yet in U-Boot. Meanwhile I don't think you should introduce a new Kconfig option, you could keep the hacky U-Boot style and just add an #if defined(CONFIG_MACH_SUN50I) || defined(CONFIG_MACH_SUN50I_H6) to the two places instead.
IIRC, the calibration is only needed for the eMMC though, so we'd need to check that against the MMC number too.
