[U-Boot] [PATCH 15/33] x86: sandbox: pch: Add a CONFIG option for PCH

[Simon Glass]

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.
