Subject: [PATCH 2/4] hw_random: bcm63xx-rng: move register definitions to driver

arch/mips/include/asm/mach-bcm63xx/bcm63xx_regs.h contains the register
definitions for this random number generator block, incorporate these
register definitions directly into the bcm63xx-rng driver so we do not
rely on this header to be provided.
