Vendor property setter takes string as vendor value but cpudefs use uint32_t vendor[123] fields to define vendor value. It makes it difficult to unify and use property setter for values from cpudefs.
To allow simplify code by using vendor property setter, vendor[123] fields are converted into vendor[13] array to keep its value. And vendor property setter is used to access/set value on CPU.
