platform/x86: touchscreen_dmi: Add EFI embedded firmware info support
Sofar we have been unable to get permission from the vendors to put the firmware for touchscreens listed in touchscreen_dmi in linux-firmware. Some of the tablets with such a touchscreen have a touchscreen driver, and thus a copy of the firmware, as part of their EFI code. This commit adds the necessary info for the new EFI embedded-firmware code to extract these firmwares, making the touchscreen work OOTB without the user needing to manually add the firmware.
