params: add Z2E to known handheld GPUs
gets rid of the extra unused fields for the Z2E (Strix/890m) similar to the other Z-series chips and Vangogh when using the "full" layout
Before:
After:
I wonder if we can figure this out programmatically instead.
If these fields aren't available they should report 0xffff like we check here [src/amdgpu.cpp:L21](https://github.com/flightlessmango/MangoHud/blob/5399bf1a184ce41ff55125e4a24b978392025d24/src/amdgpu.cpp#L73C1-L73C61)
that does sound smarter, I think all of them except for gpu_voltage report as 0xffff (gpu_voltage reports as 0). I can try implementing something based off your idea instead.
Seems safe to assume 0 for voltage also means unavailable
sorry, haven't forgotten this. will work on it this week.
