Removing: uart3_defconfig: Now uart3 can be selected using menuconfig, removing separate config for uart mode. Doing uart boot is not straight forward as ROM uses uart3 as default serial console. In order to boot to prompt, concole in both u-boot and kernel needs to be changed. qspiboot_defconfig: The only advantage of enabling QSPI_BOOT is selecting env in QSPI. Eventually env needs to be selected by menuconfig so removing qspiboot_defconfig. qspiboot can be done using dra7xx_evm_defconfig.

Summary
=======
This document covers various features of the 'dra7xx_evm' build and some
related uses.
eMMC boot partition use
=======================
It is possible, depending on SYSBOOT configuration to boot from the eMMC
boot partitions using (name depending on documentation referenced)
Alternative Boot operation mode or Boot Sequence Option 1/2. In this
example we load MLO and u-boot.img from the build into DDR and then use
'mmc bootbus' to set the required rate (see TRM) and 'mmc partconfig' to
set boot0 as the boot device.
