ipq40xx: ZTE MF287 series: move to gpio-export for modem-reset GPIO

Browse Source 
Turn the "gpio-restart" node into a "gpio-export" node for all MF287
variants, similar to the MF287 Pro. Unfortunately, there doesn't seem to be
a "power button blocker" GPIO for the MF287 and MF287 Plus, so a modem
reset always triggers a system reset.
