Subject: [PATCH] arm64: dts: exynos: Add missing gpm6 and gpm7 nodes to Exynos850

gpm6 and gpm7 nodes are missing in Exynos850 device tree. Next errors
are reported because of that:

    Missing node for bank gpm6 - invalid DTB
    Missing node for bank gpm7 - invalid DTB

Add missing nodes to make those available to use, and to fix boot
errors.

Fixes: e3493220fd3e ("arm64: dts: exynos: Add initial Exynos850 SoC support")

NOTES:
  - Recommend to apply this patch after "arm64: dts: exynos: align
    pinctrl with dtschema in Exynos850"
  - This patch also brings back two interrupts removed in "arm64:
    dts: exynos: drop incorrectly placed wakeup interrupts in Exynos850"
