[PATCH 2/2] MIPS: BMIPS: improve BCM6368 device tree

[Ãlvaro FernÃndez Rojas]

- Remove unneeded leds0 alias.
- Switch to bcm6345-l1-intc interrupt controller.
- Use interrupt-controller instead of periph_intc and cpu_intc.
- Add uart1 node.
- Single ohci and ehci nodes.
- Avoid using underscores in node names.
- Rename uart aliases to serial.
- Remove blank line in cpus node.

 v2: more device tree improvements
  - There is just ohci/ehci node.
  - Avoid using underscores in node names.
  - Use interrupt-controller for cpu_intc.
  - Rename uart aliases to serial.
  - Remove blank line.
