    vbnv: check alignment of nvram in advance
    
    Currently, erase operation only works if the region is sector-aligned.
    These asserts ensure we can erase the region when it's all used up.
    
    Erase operation can be updated to handle unaligned erases by read,
    update, write-back cycle. However, these asserts will still remain useful
    in case the adjacent region contains critical data and mis-updating it
    can cause a critical failure.
    
    Additionaly we should write a FAFT test but it's more reliable to catch
    it here since FAFT can fail in many ways.
    
    BUG=none
    BRANCH=master
    TEST=tested on samus using misaligned nvram region
