[Pdbg] [PATCH 3/3] libpdbg: For p10 do not assert special wakeup for core by default

[Amitay Isaacs]

For p10 systems, the default behaviour (for long running bmc applications)
of libpdbg is to not assert special wakeup, as the applications are not
supposed to use special wakeup.  So only assert special wakeup if
running short applications such as pdbg tool.
