ARM: am3517-evm: Migrate to SPL_OF_CONTROL

Like the other Logic PD OMAP35/DM37 boards, this board has device
tree enabled for U-Boot.  This patch converts the board to enable
SPL_OF_CONTROL and further shrinks the device tree in SPL to limit
it to UART3 (console), MMC1, i2c1, and GPIO4 (for mmc1 CD and WP).

There appears to be a bug in minicom so users may need to
switch the minicom terminal emulation to ANSI from VT102 due
to the junk that gets pushed out of the UART on startup.
