[Skiboot] [PATCH v2 3/3] platform/mambo add a heartbeat timer

[Chris Smart]

The console is very slow when using Skiboot with Mambo.

This adds a heartbeat timer as a platform quirk so that the console is
refresh more quickly. This results in Skiboot doing the right thing
without requiring custom settings in skiboot.tcl files.
