spi: spi-mem: Add Realtek SPI-NAND controller
Add a driver for the SPI-NAND controller on the RTL9300 family of
devices.
The controller supports
* Serial/Dual/Quad data with
* PIO and DMA data read/write operation
* Configurable flash access timing
There is a separate ECC controller on the RTL9300 which isn't currently
supported (instead we rely on the on-die ECC supported by most SPI-NAND
chips).
