Enable SDHCI controller support on new SpacemiT K3 SoC, while as before
only the third controller and the eMMC device has been tested which using
vendor K3 evb board. This board has not acquired support in mainline
kernel, so I've omitted the DT part patches for now.

The new SDHCI controller almost reuse the same IP as old K1 generation,
while fixed the broken 64BIT DMA issue.

Hi Ulf,
 Any chance to queue this for v6.20? I know it's a little bit late,
but the patch itself is quite simple and we've tested on evb board.
