Subject: [PATCH v2] platform/x86/intel/ifs: Update documentation to match current availability of firmware images

Firmware images necessary for certain tests in the In-field scan[1] test
suite are not available at the moment[2], and require having access to
at least an Intel customer account[3].

Update documentation to match current state, it can be updated again
when the images are finally published.

Changes since v1:
 - update commit message to clarify that only some tests need the firmware
   images, thanks Jithu for the suggestion!
