* [PATCH edk2-platforms v2 3/6] Platform/ARM: Configuration Manager for FVP

The dynamic tables framework utilizes the configuration manager
protocol to get the platform specific information required for
building the firmware tables.

The configuration manager is a platform specific component that
collates the platform hardware information and builds an abstract
platform configuration repository. The configuration manager also
implements the configuration manager protocol which returns the
hardware information requested by the table generators.

This patch implements the configuration manager support for the
FVP platform.
