SMBIOS: Allow skipping default SMBIOS generation

Browse Source 
The call to the `get_smbios_data` device operation is followed by
calls to unconditional default functions, which lacks flexibility.
Instead, have devices that implement `get_smbios_data` call these
default functions as needed.

Most `get_smbios_data` implementations are in mainboard code, and are
bound to the root device. The default functions only operate with PCI
devices because of the `dev->path.type != DEVICE_PATH_PCI` checks, so
calling these functions for non-PCI devices is unnecessary. QEMU also
implements `get_smbios_data` but binds it to the domain device, which
isn't PCI either.
