mb/google/zork: Use level-triggered IRQ for touchscreens

Browse source 
Change Raydium and ELAN touchscreen IRQ from edge to level triggering
across berknip, dalboz, ezkinil, trembyle, and vilboz variants.
Necessary for Windows driver compatibility.

TEST=build/boot Win11/Linux on ezkinil; verify touchscreen functional.
