MIPS: Add CONFIG_CPU_R5500 for NEC VR5500 series processors
We already have sufficient infrastructure to support VR5500 and VR5500A series processors. Here's a Makefile support to make it selectable by ports, and enable it for NEC EMMA2RH Markeins board. This patch also fixes a confused target help, and adds 1Gb PageMask bits supported by VR5500 and its variants.
