No need to have PIN_OFF_WAKEUPENABLE any longer here, it gets
enabled automatically after you do request_irq on it.

The second interrupt here just needs to be &omap3_pmx_core
(or &omap3_pmx_core2 depending where it's located) with the
offset to the dat1 pin from it's padconf area. For example,
on mmc3 it should be:
interrupts-extended = <&intc 94 &omap3_pmx_core2 0x46>;
So you need to look it up from the TRM to figure out the right
offset for mmc2.

I think there's a patch now in mainline tree that by default tries
to use interrupts-extended first, so this may not need to be
changed.
