[edk2-platforms][PATCH V1 2/5] Platform/Sgi: Add ProductId lookup values for RD-N2-Cfg2 Platform

["Pranav Madhu" <pranav.madhu@arm.com>]

From: Vijayenthiran Subramaniam <vijayenthiran.subramaniam@arm.com>

The RD-N2-Cfg2 platform is a quad-chip variant of the RD-N2 platform
but with reduced core count, that is, each instance of the RD-N2 chip
has four cores. This platform shares the same product and config ID
as the RD-N2 platform.

As a preparatory step towards adding support for RD-N2-Cfg2 Platfrom,
add the Product ID lookup values for GetProductID API.
