This adds support to update firmware on qspi flash present on am437x-sk-evm and am43xx-epos-evm via DFU.
On device: => setenv dfu_alt_info ${dfu_alt_info_qspi} => dfu 0 sf 0:0
On host: $ sudo dfu-util -l $ sudo dfu-util -D u-boot.bin -a u-boot.bin

v2:
- change u-boot.img to u-boot.bin.
Tested on am437x-sk-evm by flashing u-boot.bin and zImage and verified by reading back u-boot.bin and zImage in kernel. QSPI XIP boot itself is broken on u-boot mainline (even w/o this patch), hence cannot verify XIP boot using DFU.
