Always init axis mapping for the first two rel axes (#59784)
Fixes regression introduced in 2f67509b53b27dd7f51ca2aadd19605aee613a61. If evdev is used for touchpads, the abs axis movement is converted to a rel movement. Without the two relative axes initialized, the events are discarded. Axes 0 and 1 are always x/y anyway unless specifically configured otherwise.
