SMBIOS/SCONFIG: Allow devtree-defined Type 41 entries

Introduce the `smbios_dev_info` devicetree keyword to specify the
instance ID and RefDes (Reference Designation) of onboard devices.

Example syntax:

 device pci 1c.0 on	# PCIe Port #1
 	device pci 00.0 on
 		smbios_dev_info 6
 	end
 end
 device pci 1c.1 on	# PCIe Port #2
 	device pci 00.0 on
 		smbios_dev_info 42 "PCIe-PCI Time Machine"
 	end
 end

The `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` Kconfig option enables using
this syntax to control the generated Type 41 entries. When this option
is enabled, Type 41 entries are only autogenerated for devices with a
defined instance ID. This avoids having to keep track of which instance
IDs have been used for every device class.

Using `smbios_dev_info` when `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` is not
enabled will result in a build-time error, as the syntax is meaningless
in this case. This is done with preprocessor guards around the Type 41
members in `struct device` and the code which uses the guarded members.
Although the preprocessor usage isn't particularly elegant, adjusting
the devicetree syntax and/or grammar depending on a Kconfig option is
probably even worse.

+	  appropriate PCI devices in the devicetree. Instance IDs are assigned
+	  successive numbers from a monotonically increasing counter, with one
