ports: Make new ports/ sub-directory and move all ports there.

This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.

-/// \moduleref pyb
-/// \class Pin - control I/O pins
-///
-/// A pin is the basic object to control I/O pins.  It has methods to set
-/// the mode of the pin (input, output, etc) and methods to get and set the
-/// digital logic level.  For analog control of a pin, see the ADC class.
-///
-/// Usage Model:
-///
-/// All Board Pins are predefined as pyb.Pin.board.Name
-///
-///     x1_pin = pyb.Pin.board.X1
-///
-///     g = pyb.Pin(pyb.Pin.board.X1, pyb.Pin.IN)
-///
-/// CPU pins which correspond to the board pins are available
-/// as `pyb.cpu.Name`. For the CPU pins, the names are the port letter
-/// followed by the pin number. On the PYBv1.0, `pyb.Pin.board.X1` and
-/// `pyb.Pin.cpu.B6` are the same pin.
-///
-/// You can also use strings:
-///
-///     g = pyb.Pin('X1', pyb.Pin.OUT_PP)
-///
-/// Users can add their own names:
-///
-///     MyMapperDict = { 'LeftMotorDir' : pyb.Pin.cpu.C12 }
-///     pyb.Pin.dict(MyMapperDict)
-///     g = pyb.Pin("LeftMotorDir", pyb.Pin.OUT_OD)
-///
-/// and can query mappings
-///
-///     pin = pyb.Pin("LeftMotorDir")
-///
-/// Users can also add their own mapping function:
-///
-///     def MyMapper(pin_name):
-///        if pin_name == "LeftMotorDir":
-///            return pyb.Pin.cpu.A0
-///
-///     pyb.Pin.mapper(MyMapper)
-///
-/// So, if you were to call: `pyb.Pin("LeftMotorDir", pyb.Pin.OUT_PP)`
-/// then `"LeftMotorDir"` is passed directly to the mapper function.
-///
-/// To summarise, the following order determines how things get mapped into
-/// an ordinal pin number:
-///
-/// 1. Directly specify a pin object
-/// 2. User supplied mapping function
-/// 3. User supplied mapping (object must be usable as a dictionary key)
-/// 4. Supply a string which matches a board pin
-/// 5. Supply a string which matches a CPU port/pin
-///
-/// You can set `pyb.Pin.debug(True)` to get some debug information about
-/// how a particular object gets mapped to a pin.

-/// \class PinAF - Pin Alternate Functions
-///
-/// A Pin represents a physical pin on the microcprocessor. Each pin
-/// can have a variety of functions (GPIO, I2C SDA, etc). Each PinAF
-/// object represents a particular function for a pin.
-///
-/// Usage Model:
-///
-///     x3 = pyb.Pin.board.X3
-///     x3_af = x3.af_list()
-///
-/// x3_af will now contain an array of PinAF objects which are availble on
-/// pin X3.
-///
-/// For the pyboard, x3_af would contain:
-///     [Pin.AF1_TIM2, Pin.AF2_TIM5, Pin.AF3_TIM9, Pin.AF7_USART2]
-///
-/// Normally, each peripheral would configure the af automatically, but sometimes
-/// the same function is available on multiple pins, and having more control
-/// is desired.
-///
-/// To configure X3 to expose TIM2_CH3, you could use:
-///    pin = pyb.Pin(pyb.Pin.board.X3, mode=pyb.Pin.AF_PP, af=pyb.Pin.AF1_TIM2)
-/// or:
-///    pin = pyb.Pin(pyb.Pin.board.X3, mode=pyb.Pin.AF_PP, af=1)
-
-/// \method __str__()
-/// Return a string describing the alternate function.
