While probing BGX we requesting appropriate QLM for it's configuration and get LMAC count by that request. Then, while reading configured MAC values from SSDT table we need to save them in proper mapping: BGX[i]->lmac[j].mac = <MAC value> to later provide for initialization stuff. In order to fill such mapping properly we need to add lmac index to be used while acpi initialization since at this moment bgx->lmac_count already contains actual value.
