2024-10-07soc/intel/adl to jsl: Explicitly include static.h for config_of_socNicholas Chin
As per commit 865173153760 ("sconfig: Move config_of_soc from device.h to static.h"), sources that require access to the devicetree should directly include static.h so that it can be removed from device.h, eliminating unnecessary dependencies on static.h for files that only need the types and function declarations in device.h.

Commit d6dbd933 [soc/intel/cannonlake: Use SBI msg to disable HECI1] switched CNL-based mainboards from using FSP for HECI disablement to SBI msg, but this causes google/hatch to hang when attempting to unhide p2sb as part of disabling HECI1 via SBI during SMM, so switch to using PMC/IPC method.

PMC device gets hidden from PCI bus after FSP-S call. Thus, it gets removed from the root bus as leftover unused device. With change 903b40a8a46 ("soc/intel: Replace uses of dev_find_slot()"), all uses of dev_find_slot() were replaced by pcidev_path_on_root() which relies on scanning of root bus to find the requested device. Since PMC device is removed from the root bus, pcidev_path_on_root() returns NULL for it thus resulting in configuration being skipped for the PMC ultimately resulting in S3 failures. Since the PCH_DEV_PMC was just used to get to chip config, this change replaces the use of PCH_DEV_PMC with SA_DEV_ROOT. BUG=b:136861224 TEST=Verified that S3 works fine on hatch.
