Looks like you are absolutely correct - I just confirmed this from both
the AM335x-EVM schematic and the AM335x pinmux utility.

The same mistake is also in my EVMSK LCD enabling patch that is floating
around on this list at the moment.  I will fix that and resend it.
BeagleBone Black only uses the first 16 LCD pins so the dts for that is
correct.

Thanks for finding and fixing it.
