dt-bindings: pinctrl: samsung: describe Exynos850 and ExynosAutov9 wake-ups 



Older Samsung Exynos SoCs  (Exynos3250, Exynos4, Exynos5, Exynos5433)
expected pin controller node with external wake-up interrupts to have
one interrupt for multiplexing these wake-up interrupts.  Also they
expected to have exactly one such pin controller (capable of external
wake-up interrupts).

It seems however that newer ARMv8 Exynos SoCs like Exynos850 and
ExynosAutov9 have differences of their pin controllers capable of
external wake-up interrupts:
1. No multiplexed external wake-up interrupt, only direct,
2. More than one pin controller capable of external wake-up interrupts.

Add dedicated Exynos850 and ExynosAutov9 compatibles.
