arm64: zynqmp: Add cap-mmc-hw-reset and no-sd, no-sdio property to eMMC

Browse Source 
Add "cap-mmc-hw-reset" property to the eMMC DT node to perform the
eMMC device hardware reset.
Also, add "no-sd", "no-sdio" properties to eMMC DT node to skip
unwanted sd, sdio related commands during initialization for eMMC
device as this may lead to unnecessary register dump.
