rGbecaac3972f1: loader: use display pixel density for font autoselection
Summary

Calculate font size from 16 density independent pixels (dp) by using:
size = 16 * ppi/160 * display_factor

We are specifying font size 16dp, and assuming 1dp = 160ppi.
Also apply scaling factor 2 (display_factor).

Test Plan

test with different systems and resolutions

Works for me, now the font seems fine on a 2160p monitor, and there's no black bar at the bottom of the screen.

Don't really have much knowledge in this area to provide a meaningful review I'm afraid.

size = MAX(sizeof(*edid_infop), edid->SizeOfEdid);
