sdmmc: implement driver suitable for fs + bootloader

* sdmmc: begin skeletoning sdmmc driver * sdmmc: add most of SdHostStandardController * sdmmc: implement most of SdmmcController * sdmmc: Sdmmc2Controller * sdmmc: skeleton implementation of Sdmmc1Controller * sdmmc: complete abstract logic for Sdmmc1 power controller * sdmmc: implement gpio handling for sdmmc1-register-control * sdmmc: implement pinmux handling for sdmmc1-register-control * sdmmc: fix building for arm32 and in stratosphere context * sdmmc: implement voltage enable/set for sdmmc1-register-control * util: move T(V)SNPrintf from kernel to util * sdmmc: implement BaseDeviceAccessor * sdmmc: implement MmcDeviceAccessor * sdmmc: implement clock reset controller for register api * sdmmc: fix bug in WaitWhileCommandInhibit, add mmc accessors * exo: add sdmmc test program * sdmmc: fix speed mode extension, add CheckMmcConnection for debug * sdmmc: add DeviceDetector, gpio: implement client api * gpio: modernize client api instead of doing it the lazy way * sdmmc: SdCardDeviceAccessor impl * sdmmc: update test program to read first two sectors of sd card * sdmmc: fix vref sel * sdmmc: finish outward-facing api (untested) * ams: changes for libvapours including tegra register defs * sdmmc: remove hwinit
