This applies to all machine modules which have pins as arguments. Since
machine_pin_get_id() calls pin_find(), these pin arguments may be at the
moment either integer objects or Pin objects. That allows for instance to
write
uart = UART(1, tx=Pin(4), rx=Pin(5))
instead of
uart = UART(1, tx=4, rx=5)
which is consistent with other ports. Since this handling is done at a
single place in the code, extending that scheme to accept strings for named
pins is easy.
