esp8266: Convert mp_hal_pin_obj_t from pin ptr to simple integer.
Most pin I/O can be done just knowing the pin number as a simple
integer, and it's more efficient this way (code size, speed) because it
doesn't require a memory lookup to get the pin id from the pin object.
If the full pin object is needed then it can be easily looked up in the
pin table.
