Add DPLL_PIN_TYPE_INT_NCO pin type for virtual pins representing
the NCO mode of a DPLL. When connected as a DPLL input, the DPLL
enters NCO mode where the output frequency is adjusted by the host
via the PTP clock interface.

Update the fractional-frequency-offset and fractional-frequency-
offset-ppt attribute documentation to note that for INT_NCO pins
these attributes represent the DPLL's current output frequency
offset from its nominal frequency.

@Vadim: it's not clear to me if your doubts over the design choice
raised in previous iterations are still there. My understanding is there
is reasonable agreement vs the new pin type, if you have very strong
objections please raise them soonish.

@Paolo: I still have my doubts here, but the patchset has Rb tags from
Jiri, who is DPLL maintainer as well, so I think it's good to go...
