mmc: core: Fixup suspend/resume issues for UHS-I cards
Even if cards supports 1.8V I/O voltage those should anyway be initialized at 3.3V I/O according to (e)MMC, SD and SDIO specs. Some eMMC and embedded SDIO devices are able to be initialized at 1.8V as well, but it is better to be safe. Do note that initialization in this context means that the card has been completely powered off, otherwise the card will remain at the last I/O voltage level that were negotitiated. Due to the above being taken care of the suspend/resume issues for UHS-I SD-cards has been fixed.
