MLK-14884 mmc: sdhci: make DDR50 tuning optionally
DDR50 tuning is optinally defined in sd 3.0 spec. Per IC guys
suggestion, it internally already uses a fixed optimized timing
and normally does not require tuning.
Make it optionally and platform can claim SDHCI_DDR50_NEEDS_TUNING
support if it wants tuning.
