Input: psmouse - tweak PSMOUSE_DEFINE_ATTR to support raw set callbacks

Browse Source 
We want to support attr->set callbacks that may need psmouse->state to
not be updated, or may want to manually deal w/ enabling and disabling
the device.  To do that, we create __PSMOUSE_DEFINE_ATTR which enables
us to set a 'protect' argument specifying whether or not the set
callback should be protected with psmouse_disable and state setting.
