mmc: sdhci-iproc: Add ACPI bindings for the RPi
The RPi4 has an Arasan controller it carries over from the RPi3 and a newer
eMMC2 controller. Because of a couple of quirks, it seems wiser to bind
these controllers to the same driver that DT is using on this platform
rather than the generic sdhci_acpi driver with PNP0D40.
So, BCM2847 describes the older Arasan and BRCME88C describes the newer
eMMC2. The older Arasan is reusing an existing ACPI _HID used by other OSes
booting these tables on the RPi.
With this change, Linux is capable of utilizing the SD card slot, and the
Wi-Fi when booted with UEFI+ACPI on the RPi4.
