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.

Some touchpad has middle key and it will be indicated in bit 2 of packet[0]. We need to fix V4 formation's byte mask to prevent error decoding.
