riscom8: fix SMP brokenness
After analyzing the elements that save_flags/cli/sti/restore_flags were protecting, convert their usages to a global spinlock (the easiest and most obvious next-step). There were some usages of flags being intentionally cached, because the code already knew the state of interrupts. These have been taken into account. This allows us to remove CONFIG_BROKEN_ON_SMP. Completely untested.
