mmc: sdhci: skip cache invalidation if DMA is not used

If DMA(SDMA or ADMA) is not used, the cache invalidation
after reading is no need, should be skipped. Otherwise
U-Boot may hang at the cache invalidation.

Found this issue and tested this fix on DragonBoard 410c.

Fixes: commit 4155ad9aac94 ("mmc: sdhci: fix missing cache invalidation after reading by DMA")
