mmc: refactor SD startup to make it easier to support new modes
The SDcard startup process currently handles only 2 modes. To make it easier to add support for more modes, let's make the process more generic and use a list of the modes to try. The major functional change is that when a mode fails we try the next one. Not all modes are tried, only those supported by the card and the host.
