In order to load the sysfw.itb from an MMC device, clocks should be hard coded to the same value as ROM configured frequency. Clock updates cannot happen at this point as SYSFW is not yet available. So updating the clock properties for MMC nodes.
Furthermore, create a new node for the FS loader framework which we want to use to load the actual firmware file from the boot media.
