v2.3.1 — Orange Pi RV2 (SpacemiT K1) detection fix

Fixed

• Detect Orange Pi RV2 (SpacemiT K1) as SpacemiT vendor. Ky-derived kernels expose ky,x1 / ky,orangepi-rv2 in /proc/device-tree/compatible instead of spacemit,*, so the existing spacemit keyword missed them and the board fell back to the generic RISC-V logo. (#11, #12)

Verified on

• MangoPi MQ-Pro (Allwinner D1) — unchanged, still detects as Allwinner
• Orange Pi RV2 (SpacemiT K1) — now detects as SpacemiT (was generic RISC-V before)

What's Changed

• fix: Orange Pi RV2 (SpacemiT K1) を SpacemiT として検出 (#11) by @kako-jun in #12
