arm: Remove unused variable in dbg_arch_supported

bsdimp · bsdimp · commit 02b72b1540bf · 2025-11-29T02:47:49.000-07:00
Removed unused dbg_didr which had been used prior to f424213 to detect qemu unsupported debugger. I'm unsure how this slipped through my testing. Fixes: f424213 Sponsored by: Netflix
