psm: add support for evdev protocol

Both relative and absolute multitouch modes are supported.
To enable psm(4) evdev support one should:
1. Add `device evdev` and `options EVDEV_SUPPORT` to kernel config file
2. Add hw.psm.elantech_support=1 or hw.psm.synaptics_support=1 to
   /boot/loader.conf for activation of absolute mode on touchpads
3. Add kern.evdev.rcpt_mask=12 to /etc/sysctl.conf to enable psm event
   sourcing and disable sysmouse
