fangzhong.zhou 344ef2a6c6 i2c: Force DLL0945 touchpad i2c freq to 100khz
[ Upstream commit 0b7c9528fa ]

This patch fixes an issue where the touchpad cursor movement becomes
slow on the Dell Precision 5560. Force the touchpad freq to 100khz
as a workaround.

Tested on Dell Precision 5560 with 6.14 to 6.14.6. Cursor movement
is now smooth and responsive.
