openrisc: Add support for restartable sequences
Implement support for restartable sequences on OpenRISC by doing:
- Select HAVE_RSEQ in Kconfig
- Call rseq_syscall() on return to userspace when CONFIG_DEBUG_RSEQ
is enabled.
- Call rseq_signal_deliver() to fixup the pre-signal stack frame when a
signal is delivered on top of a restartable sequence critical section
