bhnd(4): Fix mips/broadcom core matching and bus pass order.

Changes:

- Fixed incorrect MIPS74k vendor ID in the bhnd core descriptor tables
- Fixed MIPS core driver's matching against MIPS/MIPS33 cores.
- Improved MIPS3302 core description.
- Enabled BUS_PASS_BUS on the bhnd nexus drivers to allow early probing
  of the MIPS core.
- Enabled BUS_PASS_CPU on the MIPS core driver to ensure correct attach
  order.
- Disabled matching of the MIPS core driver on non-SoC devices.
