MIPS: ingenic: Add newer vendor IDs 

Ingenic have actually varied the vendor/company ID of the XBurst cores
across their range of SoCs, whilst keeping the product ID & revision
constant... Add definitions for vendor IDs known to be used in some of
Ingenic's newer SoCs, and handle them in the same way as the existing
Ingenic vendor ID from the JZ4740.
