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.

The ZTE MF287 requires a different board calibration file for ath10k than
the ZTE MF287+. The two devices receive their own DTS, thus the device tree
is slightly refactored.
