[PATCH 12/25] binman: Move section padding to the parent

[Simon Glass]

Each section is padded up to its size, if the contents are not large
enough. Move this logic from _BuildSectionData() to
GetPaddedDataForEntry() so that all the padding is in one place.

With this, the testDual test is working again, so enable it.
