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. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

+ depends on X86 || SANDBOX
+ help
+ 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.
