rp2/machine_pin: Factor out pin-find code from machine_pin_make_new.

And use it in mp_hal_get_pin_obj() and machine_pin_make_new().  That way,
mp_hal_get_pin_obj() accepts both int and str objects as argument, allowing
use of a pin specifier instead of a pin object in the constructor of
devices which need a pin as parameter.

E.g. instead of

    uart = UART(0, tx=Pin(0), rx=Pin(1))

one can write:

    uart = UART(0, tx=0, rx=1)
