This initial implementation sets up support for the EMMC interfaces on the BCM2711. Only EMMC2 is tested since it is the interface of interest (connects to uSD card). MMCSD communication is functional and the boot partition of the SD card can be mounted and interacted with. Insertion/removal interrupts do not fire after initial boot, and sdstress fails with any byte size larger than 1023. 32GB card works perfectly, while 64GB card exhibits strange behaviour when interacting with VFAT filesystem.
