MIPS: BMIPS: Improve BCM6368 device tree

- 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.

[ralf@linux-mips.org: fix references in bcm96368mvwg.dts so the file keeps
building.]
