4.20-stable review patch. If anyone has any objections, please let me know.

From: Matti Kurkela Matti.Kurkela@iki.fi
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.
