ath79: Correct glinet, gl-ar300m-lite in 02_network

Previously, the board name for the GL-AR300M-Lite was incorrect
in 02_network, resulting in an unintended, fall-through condition
when initializing the network configuration.

While builds prior to commit 8dde11d521 (merged June 5, 2019)
    ath79: dts: drop "simple-mfd" for gmacs in SoC dtsi
functioned properly, the error was noted in resolving first-boot
connectivity issues related to the single-phy nature of the device
and the "swap" of eth0 and eth1 related to that commit.
