A64 requires new clock mode on SD and eMMC controllers. Not using
new clock mode causes stability issues of the driver - SPL may
occasionally fail to load u-boot from SD for some particular SD card
on some particular devices.

This series depends on "sunxi: add support for automatic delay calibration"
from my Pinebook series.

Tested on Pinebook and Pine64-LTS.

Vasily Khoruzhick (3):
  sunxi-mmc: introduce new MMC_SUNXI_HAS_NEW_MODE_SWITCH option
  sunxi-mmc: don't double clock for new mode unconditionally
  sunxi-mmc: use new mode on both controllers on A64
