Set initial_turbo=0 in config.txt on Raspberry Pi 3 (#3973)
Firmware change that set initial_turbo to 60 from the previous 0 has broken
initialization of some SD cards in U-Boot. Adjust the value in config.txt on OS
update if the value is not already set by the user, and put it to the default
config.txt.

The config.txt also contains a short comment explaining the purpose. The
purpose of it is also to make it easier to revert this change in the future if
the problem is fixed in the firmware or U-Boot.

Fixes #3965
