Chassis Location property on bmcweb

This commit implements change to publish LocationCode property
for Chassis on bmcweb.
Location code of Motherboard FRU is published via chassis schema.

LocationCode, a free form, implementation-defined string
to provide the location. This is needed so an implementation can
identify the FRU via system diagrams.

Validator has been executed and no new error has been found.
