In fact, just setting the correct ig-platform-id on Clover already does the trick on some laptops.
Another thing I just figured out is that IntelGraphicsFixup.kext injects wrong EDID in some models (mine is included). Seems that external display EDID is injected instead of the regular built-in display, which leads to the display not waking up from sleep.
So using this kext to fix Intel Graphics issues, in this case, might not be a good solution.
Edit: HD5500 works fine with ig-platform-id = 0x16260006 and _WAK patch on DSDT.
A quick search through IntelGraphicsFixup source reveals no code that injects EDID.
