The compatible string "simple-bus" is well defined in ePAPR, while
I see no documentation for the "arm,amba-bus" arnywhere in ePAPR or
Documentation/devicetree/.

DT is also used by other projects than Linux kernel.  It is not a
good idea to rely on such an unofficial binding.

This commit
  - replaces "arm,amba-bus" with "simple-bus"
  - drops "arm,amba-bus" where it is used along with "simple-bus"

All Exynos SoCs have the same syscon reboot and poweroff device nodes so
there is no need to duplicate the same on each SoC dtsi and can be moved
to a common dtsi that can be included by all the SoCs dtsi files.

Exynos has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the fact that the PMU block is actually the first
interrupt controller in the chain for RTC, kernels with this patch
applied wont have any suspend-resume facility when booted
with old DTs, and old kernels with updated DTs may not even boot.

Also, I strongly suspect that there is more than two wake-up
interrupts on these platforms, but I leave it to the maintainers
to fix their mess.
