This commit changes the I2C declarations so that the objects are
instantiated in each chip file (e.g. machine_atsamd21e18.go) and used to
define I2C0 (and similar) in the board file (e.g. board_qtpy.go). This
should make it easier to define new board files, and reduces the need
for separate *_baremetal.go files.
I have tested this the following way:
- With the LIS3DH driver example on the Circuit Playground Express and
the PyBadge.
- With the LSM6DS3 driver example on the Arduino Nano 33 IoT.
They both still work fine.
