In SD spec v6.x the SD function extension registers for performance enhancements were introduced. These registers let the SD card announce supports for various performance related features, like "self-maintenance", "cache" and "command queuing". Let's extend the parsing of SD function extension registers and store the information in the struct mmc_card. This prepares for subsequent changes to implement the complete support for new the performance enhancement features.
