Add driver for access to Intel discrete graphics card internal SPI device. Expose device on auxiliary bus by i915 and Xe drivers and provide spi driver to register this device with MTD framework. This is a rewrite of "drm/i915/spi: spi access for discrete graphics" series with connection to the Xe driver and splitting the spi driver part to separate module in spi subsystem.
