[PATCH v2 07/11] mmc: fsl_esdhc_imx: simplify 64bit check for SDMA transfers

[ fsl_esdhc commit da86e8cfcb03ed5c1d8e0718bc8bc8583e60ced8 ]
SDMA can only do DMA with 32 bit addresses. This is true for all
architectures (just doesn't apply to 32 bit ones). Simplify the code and
remove unnecessary CONFIG_FSL_LAYERSCAPE.
Also make the error message more concise.
