TWL4030: clear TWL GPIO interrupt status registers
From: Paul Walmsley <paul@pwsan.com>
twl_init_irq() does not clear the TWL GPIO ISR registers, but the PIH
ISR thinks that it has. This causes any previously-latched GPIO interrupts
to be stuck on until twl4030-gpio.c initializes, often drowning the console in
TWL4030 module irq 368 is disabled but can't be masked!
messages. This seems to be a particular problem when booting on Beagle.
