platform/x86: asus-armoury: Add power limits for ROG Strix SCAR 16 (G635LX)

Add the AC and DC power limit definitions for the ASUS ROG Strix SCAR 16
2025 (G635LX), enabling the nv_tgp, nv_dynamic_boost and ppt_pl*_* tuning
attributes on this model. Without an entry in the power_limits table the
attributes are not exposed (has_valid_limit() returns false) and the
firmware power knobs cannot be controlled.

The G635LX ships an NVIDIA RTX 5090 Laptop GPU (150 W base TGP + 25 W
Dynamic Boost = 175 W max, per the ASUS specification) and an Intel Core
Ultra 9 275HX, matching the ROG Strix SCAR 18 (G835LW). The limits are
therefore taken from the G835LW sibling entry and the ASUS specification
rather than dumped from this board's firmware.

Testing on a G635LX confirmed the attributes populate with this entry and
that writing nv_dynamic_boost changes the measured GPU power draw
(~151 W at minimum, ~169 W at maximum during inference), i.e. the limits
reach firmware.
