mfd: tps65910: Use regmap irq framework for interrupt support 

Implement irq support of tps65910 with regmap irq framework
in place of implementing locally.
This reduces the code size significantly and easy to maintain.

/*
* This is a threaded IRQ handler so can access I2C/SPI. Since all
* interrupts are clear on read the IRQ line will be reasserted and
* the physical IRQ will be handled again if another interrupt is
* asserted while we run - in the normal course of events this is a
* rare occurrence so we save I2C/SPI reads. We're also assuming that
* it's rare to get lots of interrupts firing simultaneously so try to
* minimise I/O.
