Subject: [PATCH 11/16] =?UTF-8?q?=EF=BB=BFPlatform/RaspberryPi:=20Add=20op?=
=?UTF-8?q?tion=20to=20disable=20EFI=20Memory=20Attribute=20Protocol?=

Introduce a driver that allows disabling this protocol via a HII option.
Default is enabled, which can also be overridden at build time by
changing `gRaspberryPiTokenSpaceGuid.PcdMemoryAttributeEnabledDefault`.
This should probably be done in core EDK2 though, it's clear that it
will take distros more time to catch up and suddenly breaking
compatibility like this isn't great for end users.
