board/zynqmp/kria: update readme.txt with info about qspi.bin

Browse Source 
This patch updates the documentation for Kria SOMs for reflashing
the new qspi.bin binary file.

The qspi.bin is a unified binary containing both the boot.bin and
u-boot.itb files for simplifying the reflashing process and also
enabling the BIRT for reflashing the qspi.bin image as either
"ImageA" or "ImageB".

Instructions for using these utilities to update the files
in QSPI flash can be found on the wiki link below.

Please note that since the BIRT utility requires a single file
for flashing, the qspi.bin should be used as either ImageA or
ImageB. The qspi.bin is a unified binary containing both the
boot.bin and u-boot.itb files in a single binary.

Additionally, it is possible to use u-boot for updating the
QSPI with new boot.bin and u-boot.itb images with the u-boot
commands below.

updating the QSPI boot.bin image, so this is an optional step.
