Add support for the RTL9302 SoC and the RTL9302C_2xRTL8224_2XGE
reference board.
The RTL930x family of SoCs are Realtek switches with an embedded MIPS
core (800MHz 34Kc). Most of the peripherals are similar to the RTL838x
SoC and can make use of many existing drivers.
Add in full DSA switch support is still a work in progress.

Add device_type = "cpu" to the cpu node for the rtl838x SoC. This
resolves the following dtbs_check complaint:
cpus: cpu@0: 'cache-level' is a required property

Update the node name for the UARTs to resolve the following dtbs_check
complaints:
uart@2000: $nodename:0: 'uart@2000' does not match '^serial(@.*)?$'
uart@2100: $nodename:0: 'uart@2100' does not match '^serial(@.*)?$'

The RTL838x/839x family of SoCs are Realtek switches with an embedded
MIPS core.
* RTL838x - 500MHz 4kce single core - 1Gbit ports and L2 features
* RTL839x - 700MHz 34Kc single core - 1Gbit ports and L2 features
These switches, depending on the exact part number, will have anywhere
between 8 and 52 ports. The MIPS core is wired to a switch cpu port which
has a tagging feature allowing us to make use of the DSA subsystem.
The SoCs are somewhat basic in certain areas, getting better with more
advanced features on newer series.
The switch functionality is MMIO-mapped via a large MFD region.
The SoCs have the following peripherals
* ethernet
* switch
* uart - ns16550a
* spi-flash interface
* gpio
* wdt
* led
The code was derived from various vendor SDKs based on Linux v2.6
kernels.
This patchset allows us to boot RTL838x/RTL839x units with basic support.
Most of the other drivers are already written and functional, and work to
get them upstream is already in progress.
