meta-inspur: fp5280g2: Switch ChassisType to future enum value

Since 178cae08d6(phsophor-dbus-interfaces) has converted the "Type"
property in Inventory.Item.Chassis to an enumeration, need to update
these default values in the YAML file.

Tested: built phosphor-inventory-manager successfully and the
`xyz.openbmc_project.Inventory.Manager` service has been seen.
