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.
