The JPEG decoder, that was added many years ago to display a boot-
splash in coreboot, has a few quirks. People used to do some voodoo
with GIMP to convert images to the right format, but we can also
achieve the same with ImageMagick's `convert`. The currently known
constraints are:
* The framebuffer's color format is ignored,
* only YCC 4:2:0 color sampling is supported, and
* width and height have to be a multiple of 16 pixels.
Beside that, we can only display the bootsplash if it completely
fits into the framebuffer. As the latter's size is often decided
at runtime, we can't do much more than offering an option to set
a specific size.

Also, disabling this feature results soc to enter PC2 and lower

Note: C1 demotion heuristics used EPB parameter to balance between power
and performance, i.e. low threshold when EPB is low in-order to get C1
