spi: amlogic: add driver for Amlogic SPI Flash Controller



This driver provides support for the SPI mode of the Amlogic
Flash Controller. It supports both SPI NOR flash and SPI NAND
flash. For SPI NAND, the Host ECC hardware engine can be enabled.

The controller implements the SPI-MEM interface and does not
support generic SPI.
