[coreboot] [PATCH] Kconfig HT

[mylesgw]

There's no reason for a board without HyperTransport to compile it in.  This
patch removes it (saving 1K after compression.)

I would have liked to set HYPERTRANSPORT_PLUGIN_SUPPORT the same way, but
couldn't figure out how.  I don't think plugin support for HT makes sense...

kbuildall tested.
