Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780
commit e8b22d0a329f0fb5c7ef95406872d268f01ee3b1 upstream. Like Fujitsu CELSIUS H760, the H780 also has a three-button Elantech touchpad, but the driver needs to be told so to enable the middle touchpad button. The elantech_dmi_force_crc_enabled quirk was not necessary with the H780. Also document the fw_version and caps values detected for both H760 and H780 models.
