This commit updates UP.rst to reflect changes over the past few years,
including the advent of userspace RCU libraries for constrained systems.

The UP.rst file calls for locks acquired within RCU callback functions
to use _irq variants (spin_lock_irqsave() or similar), which does work,
but can be overkill. This commit therefore instead calls for _bh variants
(spin_lock_bh() or similar), while noting that _irq does work.
