MdeModulePkg/SdMmcPciHcDxe: Do not map memory for non DMA transfer
Driver code used to map memory for DMA transfer even if host doesn't
support DMA. This is causing memory corruption when driver transfers
data using PIO. This change refactors the code to skip call to
PciIo->Map for non DMA transfers.
