[edk2-platforms][PATCH 1/1] RPi4: add descriptive errors in PlatformRegisterOptionsAndKeys

["Andrei Warkentin" <andrey.warkentin@gmail.com>]

I have reports of debug builds sitting with an ASSERT inside
PlatformRegisterOptionsAndKeys, but have not been able to verify.
Let's log errors to help diagnose this in the future.
