mmc: sdhci: Allow disabling of SDMA in SPL

Rockchip emmc devices have a similar issue to Rockchip dwmmc devices,
where performing DMA to SRAM later causes issues with suspend/resume.

Allow us to toggle SDMA in SPL for sdhci similar to ADMA support, so we
can ensure DMA is not used when loading the SRAM code.
