- 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.

building.]

On many MIPS systems the endianness of IP blocks is kept the same as
that of the CPU by the hardware. This includes the system controllers
on these systems which are controlled via syscon which uses the regmap
API which used readl() and writel() to interact with the hardware,
meaning that all writes are converted to little endian when writing to
the hardware. This caused a bad interaction with the regmap core in big
endian mode since it was not aware of the byte swapping and so ended up
performing little endian writes.
Unfortunately when this issue was noticed it was addressed by updating
the DT for the affected devices to specify them as little endian. This
happened to work since it resulted in two endianness swaps which
cancelled each other out and gave little endian behaviour but meant that
the DT was clearly not accurately describing the hardware.
The intention of commit 29bb45f25ff305 (regmap-mmio: Use native
endianness for read/write) was to fix this by making regmap default to
native endianness but this breaks most other MMIO users where the
hardware has a fixed endianness and the implementation uses the __raw
accessors which are not intended to be used outside of architecture
code. Instead use the newly added native-endian DT property to say
exactly what we want for these systems.

Most of the supported chips use legacy (non-DT) bootloaders, so they will
need to select an appropriate builtin DTB at compile time until the
bootloader is updated. Provide suitable DTS files, and a means to compile
one of them into the kernel image.
