ARM: exynos: enable multiplatform support
This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.
The multiplatform variant has a number of limitations at the moment:
* It only supports DT-enabled machines. This is not a problem in
the long run, as non-DT machines for exynos are going away.
The main problem here is that the gpio code and the exynos_eint
irqchip are not multiplatform capable but still required for
ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
multiplatform.
The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.
