[PATCH 1/2] dt-bindings: pinctrl: samsung: Fix interrupt constraint for variants with fallbacks

[Krzysztof Kozlowski]

Commit 904140fa4553 ("dt-bindings: pinctrl: samsung: use Exynos7
fallbacks for newer wake-up controllers") added
samsung,exynos7-wakeup-eint fallback to some compatibles, so the
intention in the if:then: conditions was to handle the cases:

1. Single Exynos7 compatible or Exynos5433+Exynos7 or
   Exynos7885+Exynos7: only one interrupt

2. Exynos850+Exynos7: no interrupts

This was not implemented properly however and if:then: block matches
only single Exynos5433 or Exynos7885 compatibles, which do not exist in
DTS anymore, so basically is a no-op and no enforcement on number of
interrupts is made by the binding.

Fix the if:then: condition so interrupts in the Exynos5433 and
Exynos7885 wake-up pin controller will be properly constrained.
