The GPIOs deliver enough current, but what about the voltage to drive the gate? The CMOS gate guarantees to source up to 8mA at 2.9V (= 3.3V - 0.4V). The TTL ports - the one without the pink 3.3V box in the board reference picture - guarantees the same current but only on 2.4V. The 2.4V is stated as a minimum... nevertheless, choosing a N MOSFET with an Rds(on) <=2.4 gives full freedom in pin selection.
I wondered any way why a PNP transistor... that's why I asked for a bit more context.
