qualcommax: ipq8072: assign NVMEM MAC addresses for Linksys MX5300

Browse Source 
While the base NVMEM cell (hw_mac_addr) is already defined in the device tree, it was not being utilized by the actual interfaces.

This patch completes the kernel-level MAC assignment by:

1. Correcting the label-mac-device alias to point to the WAN port (&swport5), ensuring the system reports the sticker MAC address correctly.
2. Assigning the base MAC address (offset 0) to the WAN port (&swport5).
3. Assigning the base MAC address (offset 1) to the LAN ports (&swport1 - &swport4).
4. Configuring the proper NVMEM cell references for the PCIe-attached QCA9984 radio (offset 2) and the built-in ATH11K radio (offset 3).

This eliminates the need for post-boot MAC address manipulation and ensures robust, predictable interface initialization.
