x86: sandbox: pch: Add a CONFIG option for PCH
At present this uclass is selected only on x86. In order to add a test for
it, it must also support sandbox. Create a new CONFIG_PCH option and
enable it on x86 and sandbox.

+ Most x86 chips include a PCH which is responsible for handling
+ parts of the system not handled by that CPU. It supersedes the
+ northbridge / southbridge architecture that was previously used. The
+ PCH allows for higher performance since the memory functions are
+ handled in the CPU.
