ipq40xx: ZTE MF287 series: move to gpio-export for modem-reset GPIO
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. Signed-off-by: Andreas Böhler <dev@aboehler.at> (cherry picked from commit 053f8f92d1395fa5d33b0b8f2fef44a4b926c112)
