I think I disabled this because I was wary of uncontrolled charging while
suspended. The SDG bootloader does have specific code to control charging
and the LEDs while suspended, but AFAIK it is not currently working.

Nonetheless, I've modified the patch.

Interestingly, the SDG bootloader seems to use LED interrupts to
periodically wake up during suspend. At last, that would explain why the
LED GPIOs are inputs, not outputs.
