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.
