[LINUX] Fix touchscreen

The DSDT entries for the P2 Max are broken, but Github user PeterCxy has built a CPIO override which resolves the problem.


  1. Download the latest acpi_override file from his releases page
  2. Add the acpi_override file to the root of your EFI partition (aka /boot)
  3. Add an initrd=/acpi_override kernel option to your boot manager - above any other initrd entries (GRUB_CMDLINE_LINUX in /etc/default/grub for grub; /boot/loader/entries/* for systemd-boot)
