Subject: [PATCH] ieee1275 : Converting plain numbers to constants in Vec5
This patch converts the plain numbers used in Vec5 properties to
constants.
1. LPAR : Client program supports logical partitioning and
associated hcall()s.
2. SPLPAR : Client program supports the Shared
Processor LPAR Option.
3. CMO : Enables the Cooperative Memory Over-commitment Option.
4. MAX_CPU : Defines maximum number of CPUs supported.
