clean up the following changes and bring to master:

  • gateware/i2c_master: support builds with + without touch scanning
  • gateware/cal: forward touch0-7 over debug uart to cal tool for debugging
  • cores/touch_cv: add a simple example of controlling CV outputs with touch

example build:

make BOARD=icebreaker CORE=touch_cv HW_REV=HW_R33 TOUCH=TOUCH_SENSE_ENABLED prog

users should build with TOUCH=TOUCH_SENSE_ENABLED otherwise the interface will wire all touch sense lines to zero
