ARM: dts: am3517-evm: Fix misc pinmuxing
[ Upstream commit 942da3af32b2288e674736eb159d1fc676261691 ] The bootloader for the AM3517 has previously done much of the pin muxing, but as the bootloader is moving more and more to a model based on the device tree, it may no longer automatically mux the pins, so it is necessary to add the pinmuxing to the Linux device trees so the respective peripherals can remain functional.
