HID: uclogic: Use Rx and Ry for touch strips

Currently, HUION devices use ABS_WHEEL as the usage for touch strips.

There are 2 main issues with this approach:

The first one is that the descriptor for touch rings
(uclogic_rdesc_v2_frame_touch_ring_arr) also uses ABS_WHEEL.
>From user-space it is impossible to know which device sends the events.

The second one is that Wacom uses ABS_RX/ABS_RY to notify events from
touch strips and user-space was designed to handle those axes.

Change the usage of touch strips to Rx/Ry to fix both issues.
