This commit introduces support for generating SMBIOS Type 9 (System Slot)
tables using a hybrid approach:
1. Explicit Device Tree definitions:
Child node under '/smbios/smbios/system-slot' will be interpreted as
individual slot definitions.
- Each child represents a slot (e.g., isa, pcmcia, etc.).
- Properties follow the SMBIOS specification using lowercase
hyphen-separated names such as 'slot-type', 'slot-id',
'segment-group-number', 'bus-number', 'slot-information', etc.
- This approach allows full customization of each system slot and is
especially suitable for platforms with well-defined slot topology.
2. Automatic detection fallback:
If child node under '/smbios/smbios/system-slot' does not exist, the
implementation will scan the entire device tree for nodes whose
'device_type' matches known slot-related types ("pci", "isa", "pcmcia",
etc.).
- When a match is found, default values or heuristics are applied to
populate to the System Slot table.
- This mode is useful for platforms that lack explicit SMBIOS nodes
but still expose slot topology via standard DT conventions.
Together, two approaches ensure that SMBIOS Type 9 entries are available
whether explicitly described or automatically derived.
