Right now the HDMI properties like vendor and product ids are hardcoded in the function "intel_hdmi_compute_spd_infoframe()".
ret = hdmi_spd_infoframe_init(frame, "Intel", "Integrated gfx").
This patch enables the possibility of setting vendor and product id fields of the Infoframe structure in the userspace instead of hardcoding in the kernel, and this will help display manufacturers preload picture configurations for the devices.
The changes has been Tested by an IGT testcase which got floated. https://patchwork.freedesktop.org/series/89852/.
