Some brcmstb GPIO controllers can be used to wake from suspend, so use
the de facto standard property 'wakeup-source' to mark the nodes of
controllers with that capability.
Also document interrupts-extended, which will be used for wakeup
handling because the interrupt parent for the wake IRQ is different
from the regular IRQ.
While we're at it, a few more fixes: We don't actually use the
"interrupt-names" property, so remove it from the listed optional
properties and from the examples. And since we're modifying the
examples, also follow Brian's suggestions to:
- change #gpio-cells, #interrupt-cells, and brcm,gpio-bank-widths from
hex to dec
- use phandles
