spi: spi-mem: Add Realtek SPI NOR flash controller driver
Add a spi-mem driver for the SPI NOR Flash Controller (SFC) found on
Realtek DHC SoC. SFC supports Dual I/O.
Implement the exec_op API for regular control commands and the dirmap API
for hardware-accelerated read/write operations.
The controller is described by three register ranges. The first one (ctrl)
holds the control registers. The second one (dma) holds the DMA engine
registers, used to transfer the payload between the flash and main memory.
The third range is the memory aperture (dirmap) that maps the flash
contents.
