Add the SPI-NAND controller on the RTL9300 family of devices. This
supports serial/dual/quad data width and DMA for read/program
operations.

Notes:
    Changes in v4 & v5:
    - none
    Changes in v3:
    - drop wildcard rtl9300-snand compatible
    - drop clock-names
    Changes in v2:
    - Add clocks

The binding patch got an r-by from Krzysztof. The driver itself was 
applied by by Mark, it did have a problem but that was fixed with 
another patch. So from my point of view this is good to go (please speak 
up if I've missed something).

I do intend to add a few more compatibles for other RTL chips that use 
this spi-nand controller but I'll do that as new patches.
