[Fix] - 3.5" HDMI 1920x1080 fix lower resolution

Hi there. I’ve bought this 3.5" HDMI Display-MPI3508 it has native resolution of 480x320 but via EDID it presents 1920x1080@60.

I’ve been forced different resolution on Armbian Jammy inserting the line in /boot/armbianEnv.txt

extraargs=video=HDMI-A-1:896x504M@87

720x480 works only @60hz

extraargs=video=HDMI-A-1:720x480@60

Here a picture of the screen for Raspberry Pi 3 but it fits on BPI-M5.
