spmi: pmic_arb: add support for interrupt handling

The Qualcomm PMIC Arbiter, in addition to being a basic SPMI controller, also implements interrupt handling for slave devices. Note, this is outside the scope of SPMI, as SPMI leaves interrupt handling completely unspecified. Extend the driver to provide a irq_chip implementation and chained irq handling which allows for these interrupts to be used.
