wifi: mt76: permit to load precal from NVMEM cell for mt7915

Browse Source 
Permit to load precal from NVMEM cell for mt7915. The NVMEM cell must be
named "precal" to be correctly loaded.

NVMEM cell must already account the correct offset and be placed after
the EEPROM as the function expect the data right from the start.
