This patch adds support for the Nios handshake private feature on Intel PAC (Programmable Acceleration Card) N3000. The Nios is the embedded processor on the FPGA card. This private feature provides a handshake interface to FPGA Nios firmware, which receives retimer configuration command from host and executes via an internal SPI master (spi-altera). When Nios finishes the configuration, host takes over the ownership of the SPI master to control an Intel MAX10 BMC (Board Management Controller) Chip on the SPI bus. For Nios firmware handshake part, this driver requests the retimer configuration for Nios firmware on probe, and adds some sysfs nodes for user to query the onboard retimer's working mode and Nios firmware version. For SPI part, this driver adds a spi-altera platform device as well as the MAX10 BMC spi slave info. A spi-altera driver will be matched to handle the following SPI work.
