From: Kishon Vijay Abraham I <kishon at ti.com>
Add pinmux configuration for SD card slot and eMMC device
found on TI's DRA74x EVM.
Only the default modes are supported. For higher speed modes
(UHS and HS200) to function, we need full fledged IODelay support
in kernel. IODelay support is yet to be added.

[nsekhar at ti.com: rebase to mainline/master, use IOPAD() macro,
update commit message]
