mfd: twl - twl6030 enable all irq sources (temp fix)
This patch enables all twl6030 interrupt sources by default,
allowing boards seeing a marginal overcurrent to acknowledge it.
The correct solution is to find the cause of high current from
one of the regulators seen on all Panda boards probably and
reduce the load, but this patch will get around the spontaneous
OFF seen on Panda for now.
