device: Use __pci_0_00_0_config in config_of_soc()
This change updates the definition of config_of_soc() to a macro that
expands to __pci_0_00_0_config instead of accessing the config
structure by referencing the struct device. This allows linker to
optimize out unused portions of the device tree from early stages.
With this change, bootblock .text section size drops as follows:
Platform | Size without change | Size with change | Reduction |

As static.h is now included in device.h which gets pulled in during
the unit tests, a dummy static.h is added under tests/include.
