Hide the AxeOS Voltage Regulator Temperature on hardware that does not support

[skot]

Only Bitaxe with the TPS546 voltage regulator support measuring this temp. On other machines the AxeOS measurement should be hidden.

Hardware that has the TPS546:

• Ultra 207 and higher
• Supra 402 and higher
• Hex 302 and higher

Rather than look at the specific board versions we can just check if the value is greater than the initialized value of 0. A temperature under 0 seems unlikely even in sub 0 temperatures.
