am335x-evm, am335x-evmsk and am335x-beaglebone are currently relying on
pinmux set by the bootloader to set the correct value for mmc1. Fix
this by adding pinmux data for the same in kernel.

We went one pin too far on the Beagle's here:
0x9a0 ( mcasp0_aclkr.mmc0_sdwp ) = Routed to P9_42, (muxed with C18,
to a shared pin on the header), so not connected to the microSD
socket...
https://github.com/beagleboard/beaglebone-black/blob/master/BBB_SCH.pdf
Looking at this evm schematic, it looks like 0x9a0 should be removed
too, but I'm not sure on all revisions:

Apologies for not replying here earlier.
You're right. The sdwp pin needs to be removed from bone and evm sk. It
needs to stay only for gp evm. Looks like this needs to be fixed for
bone in U-boot also.
Thanks,
Faiz
