This patch adds openpiton-riscv64 SOC support. In particular, this board supports a standard bootflow through zsbl->u-boot SPL-> opensbi->u-boot proper->Linux. There are separate defconfigs for building u-boot SPL and u-boot proper

- V6 . separate defconfigs for u-boot and SPL . eliminate debug console output . style updates - V7 . update Kconfig for OpenPiton board . SPL defconfig updates
