[HAL][LL][SDMMC] Fix various bugs identified in MMC driver - Take in account the voltage range in the CMD1 command. - Add new LL function to have correct response for MMC driver. - Update the driver to have all fields correctly initialized. - Add a internal to manage the power class and call it before to update speed of bus width. - Add new API to get the value of the Extended CSD register and populate the ExtCSD field of the MMC handle.
