platform/x86: asus-wmi: add support for showing middle fan RPM

Browse Source 
Some newer ASUS ROG laptops now have a middle/center fan in addition
to the CPU and GPU fans. This new fan typically blows across the
heatpipes and VRMs betweent eh CPU and GPU.

This commit exposes that fan to PWM control plus showing RPM.
