Pin 104 claimed by MMC1

[traversjames]

In am335x-bone-common.dtsi pin 104 is being claimed by the MMC1 device even though it is not associated with the SDcard connector on the board schematic:
0x1A0 (PIN_INPUT_PULLUP | MUX_MODE7) /* mcasp0_aclkr.gpio3_18 */

This is introduced in a8d5991 where all mmc pins are initially assigned.

A guess as to why this happened is maybe confusion of the CD pin (gpio0_6) with gpio0_7. gpio0_7 is tied to this gpio3_18 pin on the board on P9_42 so maybe both pins were claimed to avoid conflict. It doesn't seem necessary and claims a useful PRU/Mcasp resource.

Since that patch seems to be signed-off by several TI folks, can you send a note to the Beagle mailing list (http://beagleboard.org/discuss) and CC them? I wouldn't want to fix it without knowing why they put it in and then not having it fixed everywhere.
