SInput: Mapping updates for GCUltimate/ProGCC

- In previous firmwares for my gamepads, the buttons were sent in a static order for ABXY.
- To better be 'transparent' to the driver and save myself from future fragmentation, I am updating the mappings to be consistent, where the HID report should always expect to receive the button inputs based on cardinal button directions rather than button labels.
- This better aligns with the existing 'fallback' behavior of a generic device.
- Coincides with firmware library update: HandHeldLegend/HOJA-LIB-RP2040#30
