The RPi4 has an Arasan controller it carries over

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 OSs booting these tables on the RPi.

With this change, Linux is capable of utilizing the
SD card slot, and the wifi when booted with
UEFI+ACPI on the rpi4.

This is uber nit picking, but can you try to be consistent in how you
capitalize words throughout your commit subject and use common writing
such as: RPi, Wi-Fi, OSes.
