This patch removes all *_PLUGIN_SUPPORT options and replaces most

*_SUPPORT options with NO_*_SUPPORT options.  This means that you have
to specify that you want a smaller BIOS, otherwise you get full
functionality.

HyperTransport is the only exception for a couple of reasons.  HT
requires a mainboard.h file which not all mainboards have, and it's
less likely to be "plugged in" to a board that doesn't have some
onboard HT.

It also fixes a trivial typo in Kconfig (paylaod -> payload)
