mfd: twl4030-core irq simplification
Simplify twl4030 IRQ handling by removing a needless custom flow
handler. The top level IRQs, from the PIH, are well suited for
handle_simple_irq() ... they can't be acked or masked.
Switching resolves some issues with how IRQs were dispatched.
Notably, abuse of desc->status, IRQ accounting, and handling
of various faults.
In short, use standard genirq code.
Drivers that request_irq() to the PIH will need to pay more
attention to things like setting IRQF_DISABLED (since it's
no longer ignored), and making I2C calls from handlers (you'll
need a lockdep workaround).
