mmc: sdhci: Set DMA mask when adding host
Set the DMA mask in sdhci_add_host() after we determined the
capabilities of the device. 64-bit devices in particular are given the
proper mask that ensures bounce buffers are not used.
Also disable DMA if no proper DMA mask can be set, as the DMA-API
documentation specifies.
