ArmPlatformPkg: remove PL180 SD controller driver

The PL180 SD host controller driver is only used on emulated ARM
platforms, uses an obsolete version of the MMC host protocol and
does not adhere to the UEFI driver model.

It has been moved into edk2-platforms alongside the only platforms
that use it, so we can drop it from the EDK2 core repository.
