robert-hh 29e9573de7 esp32: Use always machine_pin_get_id for getting a Pin id. ...

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.
