* Increase mt7986 ATF reserved memory to 256 kiB to follow the linux kernel and Trusted Firmware-A changes. * Remove unnecessary reserved memory region for the WiFi hardware. The u-boot can not drive the WiFi hardware. Hence we don't need to keep this memory region. * Remove useless node labels and update comments.
