The et1macaddr NVRAM variable contains a MAC address for gmac1 on Asus
RT-AC88U. Add NVMEM cell for it and reference it in the gmac1 node.
The Broadcom GBit BCMA driver will issue the MAC address for gmac{0,1,2}
retrieved from et{0,1,2}mac from SPROM without this but let's explicitly
define it as mac-address on the devicetree.
Refer to drivers/net/ethernet/broadcom/bgmac-bcma.c:147.
