mfd: tps65910-irq: Add devicetree init support

This change changes the tps65910-irq code to use irqdomain, and support initialization from devicetree. This assumes that the irq_base in the platform data is -1 if devicetree is used.

---
v4: moved driver to use irq domains
v3: no change from v2.
v2: split off irq specific changes based on previous review comments
