I notice that here -- and elsewhere! -- you're not adding an IRQ
resource. We should get rid of the TWL4030_MODIRQ_* and *_PWRIRQ_*
symbols ... I think you'll observe that the twl_has_gpio() branch
is a slightly better model than the original twl_has_rtc() code,
in terms of how to add each child that uses interrupts.
In this case you can add an IRQ resource 4 more than the base IRQ
(GPIO using 0 more), switch the relevant USB code over so that it's
using platform_get_irq(), and comment out TWL4030_MODIRQ_USB in
the header (now that nobody's using it).
I'll send a small IRQ cleanup patch doing that for the RTC in a
bit, after I sanity check it.
