For i2c.py: the accelerometer now uses the new I2C driver so need to
explicitly init the legacy i2c object to get the test working.
For pyb1.py: the legacy pyb.hid() call will crash if the USB_HID object is
not initialised.
In tests/pyb is now a suite of tests that tests the pyb module on the
pyboard. They include expected output files because we can't run
CPython on the pyboard to compare against.
run-tests script has now been updated to allow pyboard tests to be run.
Just pass the option --pyboard. This runs all basic, float and pyb
tests. Note that float/math-fun.py currently fails because not all math
functions are implemented in stmhal/.
