armv8: fsl-lsch2: enable snoopable sata read and write
By default the SATA IP on the ls1043a/ls1046a SoCs does not
generating coherent/snoopable transactions. This patch enable
it in the SCFG_SNPCNFGCR register along with sata axicc register.
In addition, the dma-coherent property must be set on the SATA
controller nodes.
