utpms(4): fix geyser 2 y_sensors

[Tobias Heider]

Hi,

the newer Geyser 2 touchpad has only 9 sensors in the Y-direction instead
of 16 like the other Apple touch pads.
The driver sets sc_y_sensors correctly and then immediately overwrites
it with the wrong default.
I think we should first set the defaults and then treat the special
cases.

ok?
