Source-scoped the remaining capability ports while wifi builds: - TRNG: rv1106 trngv1 registers byte-identical to rk3588 → ~2-line compat add reusing mainline rk3588_soc_data/rk3588_rng_read. Near-free hw entropy. - GMAC: integrated EPHY (0x1234d400) already in mainline net/phy/rockchip.c; only the dwmac-rockchip rv1106 GRF ops + board node needed. - OTP: add rv1106_data to mainline rockchip-otp.c (also feeds GMAC bandgap). - audio/crypto-v3/npu/mailbox/pvtm scoped with verify steps.
