tinkerboard2: introduce adapter for Asus Tinker Board 2 (rk3399)

[gen2thomas]

Solved issues and/or description of the change

The gpio and pwn definitions differ from Tinkerboard with rk3288, so a new adaptor was introduced.

Additionally introduce common:

• analogpintranslator
• digitalpintranslator
• pwmpintranslator
• busnumbervalidator, used for i2c and spi

Additionally:

• small fixes in logging text
• small fixes in test function name
• use the new common translators and validator for, if applicable:
  • beaglebone & pocketbeagle
  • chip
  • dragonboard
  • joule
  • jetson
  • nanopi
  • rasp
  • rockpi
  • up2
  • tinkerboard
  • tinkerboard2

Manual test

• OS and Version (Win/Mac/Linux): Linux
• Adaptor(s) and/or driver(s):
  • gpio (see new example, tested with all header pins)
  • onewire (DS18B20)
  • i2c (YL-40)
  • pwm (with oscilloscope)

Checklist
