Add a sandbox driver and PCI-device emulator for p2sb. Also add a test
which uses a simple 'adder' driver to test the p2sb functionality.

Changes in v6:
- Correct a few unrelated defconfig changes
- Drop unwanted debug printf()
Changes in v5: None
Changes in v4:
- Drop change to message about a missing uclass
- Drop empty operations struct since p2sb does not need it
- Drop pmic_pm8916 driver name and use a sandbox name instead
- Split out mmio changes into a separate patch
Changes in v3:
- Fix build errors in sandbox_spl, etc
Changes in v2: None
