Damien George 39d50d129c ports: Add SoftI2C and SoftSPI to machine module where appropriate.
Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances.  Such
construction is now split to explicit soft and non-soft types.

This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.

This is a breaking change for use of software-based I2C and SPI.  Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:

    machine.I2C(-1, ...)            ->  machine.SoftI2C(...)
    machine.I2C(scl=scl, sda=sda)   ->  machine.SoftI2C(scl=scl, sda=sda)

    machine.SPI(-1, ...)            ->  machine.SoftSPI(...)
    machine.SPI(sck=sck, mosi=mosi, miso=miso)
                        ->  machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)

Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.
