Sergey Matsievskiy eb6f2745b7 flash/nor: add DesignWare SPI controller driver
Driver for DesignWare SPI controller, found on many SoCs (see compatible
list in Linux device tree bindings
Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml). This
implementation only supports MIPS as it was the only one available for the
tests, however, adding support for other architectures should require only
few adjustments. Driver relies on flash/nor/spi.h to find Flash chip info.
Driver internal functions support 24bit addressing mode, but due to
limitations of flash/nor/spi.h, it is not used. The reported writing speed
is about 60kb/s.
Lint, sanitizer and valgrind reported warnings were not related to the
driver.
