[PATCH 2/2] gpio/aspeed-sgpio: don't enable all interrupts by default

[Jeremy Kerr <jk@xxxxxxxxxxxxxxxxxxxx>]

Currently, the IRQ setup for the SGPIO driver enables all interrupts for
dual-edge trigger mode. Since the default handler is handle_bad_irq, any
state change on input GPIOs will trigger bad IRQ warnings.

This change applies sensible (disabled) IRQ defaults.
