wifi: mt76: permit to use alternative cell name to eeprom NVMEM load

Browse Source 
Generilize mt76_get_of_eeprom_from_nvmem to use alternative cell name by
passing the cell name as an arg and expose it.

Rename it to mt76_get_of_data_from_nvmem to better reflect the now more
generic usage.

This is to permit driver to load additional cell, like precal cell.
