Subject: [PATCH] elput: Fix issue of pointer rotation not being set on startup

elput_input_pointer_rotation_set may be getting called before input
devices are actually added, so we need to be able to set pointer
rotation when a device actually gets added.

To fix this, we will store the requested input rotation value, and
apply it at the time of input device creation.

NB: The current case is that the wl_drm module will apply existing
output rotation before Input has completely initialized, thus any
calls to set the pointer rotation there will not succeed as input
devices have not been created yet.

@fix
