Woops, sleepydust hasn't cleared from my eyes yet, the normal mode is being adjusted, not idle mode. |

I verify that this PR fixes the issue on the two units I have. I'm in the US. |

This addresses spurious multiple touches experienced with the batch of 3.5" touchscreens with the silkscreen misspelling of Capacitive as "Capaciptive".
There's a forum post showing a possible fix along with others experiencing the issue: https://forums.adafruit.com/memberlist.php?mode=viewprofile&u=220642
This datasheet page shows the calculation for internal touch oscillator frequency during Normal Mode and Idle Mode:
The original code uses some values that don't match the code comment either:
I've set both to 60Hz (only really adjusting normal mode)
There's an interest from the wider world to understand why 70Hz was chosen, if someone knows then stick it in the forum and help grow the understanding.
