boot/uboot: add qspi.bin file support

Browse Source 
u-boot has introduced a new file called qspi.bin for users who boot from a
qspi flash device.  It combines the spl/boot.bin and u-boot.itb files into a
single binary that can be written to the qspi flash.

Here is an example of how binman generates the qspi.bin:
a4c9811910

At the moment, the qspi.bin is only used for the zynqmp platform, but other
platforms may adopt it, so the buildroot support has been made in a generic
way.

This patch adds the necessary support for buildroot to install this binary.

[Tested on Kria KV260 starter kit]
