kernel: pinctrl-rockchip.c COMPILES CLEAN on 6.18 + iomux offsets cross-validated

Browse Source 
M1 pinctrl ported from vendor 5.10 (effort S, no API drift): enum, DRV/PULL/SMT
macros + 3 calc fns, case RV1106 in the 3 pull fns + RK3568 drive group, pin_banks
+ pin_ctrl, of_device_id (dropped CPU_RV1106 guard). pinctrl-rockchip.o 173KB, no
errors. iomux DRV/PULL/SMT offsets cross-validated against the upstream Simon Glass
v3 patch (match with the 0x10000 per-bank IOC base) -> the boot-critical iomux
PORT-VERIFY is retired via a 3rd independent source, no hardware. Upstream tracked
as a correctness oracle (doesn't apply to 6.18 cleanly; unmerged).

# RV1106 pinctrl support on Linux 6.18.46 (forward-ported from vendor 5.10). COMPILES CLEAN (pinctrl-rockchip.o 173688 bytes).
# iomux DRV/PULL/SMT offsets cross-validated against upstream Simon Glass v3 patch (match once the 0x10000-strided per-bank IOC base is applied).
