dt-bindings: mfd: ti,tps65910: Add wakeup-source and GPIO hogs

Device tree validation throws warnings for the TPS65911 PMIC on Tegra
boards because wakeup-source and GPIO hog nodes are not documented in
the schema, even though the hardware supports them.

Add wakeup-source property and allow child nodes that match the "-hog"
pattern.
