Split bcm_mipscore.c into bcm_bmips (BMIPS32/BMIPS3300) and bcm_mips74k
drivers. The BMIPS32/BMIPS3300 cores use a register layout distinct from the MIPS74K core, and are only found on siba(4) devices. Reviewed by: mizhka Approved by: adrian (mentor) Differential Revision: https://reviews.freebsd.org/D7791
