soc/intel/common/nvm: Allow overriding to_flash_offset() function

On apollolake, the flash is memory-mapped differently, and the default
    MMIO to flash calculation does not produce correct results. While the
    long-term solution is to rewrite the NVM functionality to keep the
    flash offset as part of its context, as a temporary measure, allow
    overriding the to_flash_offset() function by declaring it weak.
