Bug: PDF documentation doesn't build according to instructions

[Patrick Walton]

When I follow the instructions for building PDF documentation ( https://docs.u-boot.org/en/latest/build/documentation.html ) , I run into an error at the texi2pdf step (attached). It appears to have to do with the boot flow diagram of k3_current not being an acceptable format for the pdf compiler. I tested this on several releases and it appears to have appeared in the v2023.10 release and continues to the latest. I was able to build the documentation on the v2023.07 release.

Take care,

@Texinfo supports .png, .jpg, .jpeg, and .pdf images with PDF output, and none 
of those formats could be found. (.eps cannot be supported due to the design of
 the PDF format; use regular TeX (DVI output) for that.)
