configurations: yosemite4: Fix Cpu type field

The code generates inventory items according to this field.
The inventory item for a cpu according to PDI:
`xyz.openbmc_project.Inventory.Item.Cpu", but all letters in capital
creates `xyz.openbmc_project.Inventory.Item.CPU` which also conflicts
with bmcweb code.

Fixing the schema in schemas/global.json accordingly.
