n80xx-common: update include and inherit-product

if we have two files with the same name used with PRODUCT_COPY_FILES,
it takes always the first one and not the ones in the tree

This allows us to override files from smdk4412-common

  * use include instead -include wherever appropriate
    . when using "-include", make ignores a makefile which does not
      exist, with no error message
    . use "include" for all makefiles which are essential for a
      working build

  * remove include for vendor board product
    . that file not exists
