Add Sensylink CTF2301 support to the LM63 driver. CTF2301 follows the LM63-style temperature, tachometer, and PWM register layout, while using a 12-bit local temperature register and requiring the ALERT/TACH pin to be configured for tachometer input. Register an optional thermal cooling device when the device tree node provides #cooling-cells, allowing thermal zones to control the fan through the existing PWM path without changing behavior for existing LM63-family users.
