pistachio: add 4.9 kernel support

This adds kernel support for the Pistachio SoC and the Marduk (Ci40)
board which uses it.

Much of the code for Pistachio has been upstreamed however some
patches are still required to boot from the Marduk board:
 * spi bug fixes
 * dma bug fixes
 * pistachio internal clock tree bug fixes
 * spi-nand implementation
 * dts based mtd device naming scheme
 * dts backports and bug fixes
