ARC: HSDK: Enable SPI flash support
HSDK board has sst26wf016 SPI flash IC which we want to support.
Add SPI controller, CS-gpio and SPI flash nodes to hsdk device tree.
Enable corresponding options in hsdk defconfig.
For SPI write functionality to work we need [1] which
adds support of sst26xxx ICs.
