[edk2-platforms: PATCH v2 01/10] Marvell/Armada7k8k: Fix 32-bit compilation

["Marcin Wojtas" <mw@semihalf.com>]

It turned out, that the recently added features broke
ARM compilation. Fix all issues:
* Use SIGNATURE_32 only
* Do not shift address by 32-bit in ICU
* Limit memory for ARM build to 1GB and stop using non-existent PCD
