riscv: asm update for building ubifs

Fix misisng atomic and test_and_{set,clear}_bit macros to allow the ubi/ubifs code to be built for riscv. These are fairly simple but are not being used outside of ubifs on our builds.

Ben Dooks (3): riscv: add generic link for <asm/atomic.h> riscv: implement local_irq_{save,restore} macros riscv: define test_and_{set,clear}_bit in asm/bitops.h
