Remove limit on max size of PNOR TOC

Previously we assumed the TOC would never be larger than 4kb, this
limited us to <31 sections in pnor. We are getting to the point that is
not enough. To satify the github issue a change was needed in the ffs
tool to correctly build the TOC so it describes its size correctly.
Those changes can be found here: github.com/open-power/ffs/pull/14
The changes in this commit fix hostboot so that it will correctly
parse TOCs > 4kb. Resolves open-power/zaius-openpower/#57.
