dt-bindings: hwmon: Add Sensylink CTF2301

Browse Source 
Add the Sensylink CTF2301 temperature sensor and fan controller to the
LM63 family binding. The chip follows the LM63 register model and can
provide a thermal cooling device when #cooling-cells is present.

Do not provide a national,lm63 fallback because the CTF2301 is not fully
compatible with LM63. It uses different conversion-rate encodings,
extended local-temperature registers, additional fan lookup table
entries, and device-specific PWM and ALERT/TACH configuration. An older
LM63 driver would therefore not operate the device correctly.
