Re: [edk2-platforms][PATCH 1/1] RaspberryPi: get RPi4 and RPi3 building again.

["Pete Batard" <pete@akeo.ie>]

For reference, this breakage was introduced with edk2 commit 
https://github.com/tianocore/edk2/commit/b6490426e3208de7d6cbd756276a02e4329cd85a 
(MdeModulePkg: Connect VariablePolicy business logic to VariableServices).

It'll probably be worth adding a reference to it in the commit message 
during integration.

With this:
