[BUG] Sovol SV06 boot loop with SPEAKER about marlin HOT 4 OPEN

This appears to be a known issue with the SV06/GD32 motherboard:

The speaker is disabled in the configuration because of crash issues it causes with the clone processor used in the Sovol.

But the speaker still works fine and produces the beeps and sounds you would expect. For those who want it disabled you can do so in the menu and save settings to not hear anything.

Disable the SPEAKER define in your config for now.

Hi @thisiskeithb, thank you for looking into this. I am not sure if it helps, but the stock fork of Marlin that Sovol created doesn't seem to have this issue, even though the pin mapping appears identical.

Is there anything about the Sovol fork that may be worth checking?

The SV06 source code appears to be based off Marlin 2.0.9.2, so I diffed them and didn't see anything related to pins/speaker/timers that may be the culprit.

Sovol disabled USE_WATCHDOG in Configuration_adv.h, so as a temporary test, does disabling USE_WATCHDOG with SPEAKER enabled work?

Thanks for looking at this @thisiskeithb . I am pretty stacked this week, but I will see if I can find some time try this out!
