HID: alps: fix stick device not working after resume
The stick device does not work after resume, add U1_SP_ABS_MODE flag can
make the device work after resume.
This has been discovered by pure guesswork, based on how the existing code
uses
U1_TP_ABS_MODE flag on both initialization and resume.
I also tested the the patch on an ALPS touchpad without stick device, did
not
notice any side effect on suspend/resume, so I made the U1_SP_ABS_MODE flag
mandatory.
