Basically when it refers to GPIO1-7 it refers to a modem part
page 12 says
"The transceiver GPIO pins default to inputs at reset. There are no programmable pullups on these pins. Unused GPIO pins should be tied to ground if left as inputs, or if left unconnected, they should be programmed as outputs set to the low state. During low power modes, input must remain driven by MCU."
Take a look at MC1321xRM.pdf page 5-15
gpio7_oen and so on.
