PI0 W might require `over_voltage=2`

[GuillaumeBroggi]

Using pCP v10 with a second-hand Pi Zero W V1.1 consistently led to a kernel panic and fatal exception as soon as the CPU was loaded.

Same outcome with:

• different power supply, including an official one
• pCP v9.2
• piCore v15.0

However, pCP v8.2 is running fine.

Investigating the matter, it could be related to "recent" kernel updates (see raspberrypi/linux#5572), although I am not sure why.

Setting over_voltage=2 in conf.txt on the boot partition fixes the issue.

Dear @GuillaumeBroggi, Thank you so much for mentioning this. I was pretty sure that "nobody just test nothing on pi zero" as none of recent distros worked for me, now I know the reason and the fix, my pi zero is alive again. Thank you!
