Subject: [RFC PATCH 15/17] powerpc/e500: Fix up all remaining code uses of CONFIG_E500
The CONFIG_E500 config option is ambiguous and used incorrectly in many
places to refer to some combination of e500v1/v2, e500mc, and e5500.
Fix up each reference to use the correct combinations of the following
config options:
CONFIG_FSL_E500_V1_V2
CONFIG_FSL_E500MC
CONFIG_FSL_E5500
