I don't know that this is needed for the da850-evm since it doesn't
boot from sd/mmc.  It can boot from SPI, NAND or NOR Flash depending
on the config option selected, but none of them need the gpio during
SPL.  The gpio is loaded during normal U-Boot.  I will try to run some
tests to make sure it still boots in the next few days.  I know space
is getting tight in SPL.
