Subject: [v2] wlcore: add missing nvs file name info for wilink8

When working with wl18xx the nvs file is used for defining an alternate
mac address and override the default mac address that is stored inside
the wl18xx chip.

The following commits:
c815fde wlcore: spi: Populate config firmware data
d776fc8 wlcore: sdio: Populate config firmware data

Populated the nvs entry for wilink6 and wilink7 only while it is 
still needed for wilink8 as well. 
This broke user space backward compatibility when upgrading from older 
kernels, as the alternate mac address would not be read from the nvs that is 
already present in the file system (lib/firmware/ti-connectivity/wl1271-nvs.bin) 
causing mac address change of the wlan interface.

This patch fix this and update the structure field with the same default nvs file 
name that has been used before.
