[smbios] Allow access to multiple instances of SMBIOS structures
Extend the syntax for numerical SMBIOS settings from
smbios/<type>.<offset>.<length>
to
smbios/[<instance>.]<type>.<offset>.<length>
Where SMBIOS provides multiple structures with the same <type>, this
extended syntax allows for access to structures other than the first.
If <instance> is omitted then it will default to zero, giving access
to the first instance (and so matching existing behaviour).
The 16-bit SMBIOS handle (which is an alternative way to disambiguate
multiple instances of the same type of structure) can be accessed, if
required, using
smbios/<instance>.<type>.2.2:uint16
