root f8fcde6129 BC-250 40 CU unlock: kernel patch, build script, and documentation ...

Re-enable all 40 CUs on the AMD BC-250 (gfx1013 / Cyan Skillfish) via
two register writes during amdgpu driver init:

- CC_GC_SHADER_ARRAY_CONFIG: clears harvest enumeration mask
- SPI_PG_ENABLE_STATIC_WGP_MASK: enables hardware wave dispatch to all WGPs

Both required — neither alone is sufficient. Verified 1.61x compute
scaling at 1500MHz (pp512: 230 → 372 tok/s) via controlled A/B/A testing.
