[1/7,v5] trace, RAS: Add basic RAS trace event

Commit Message

Chen Gong June 11, 2014, 8:34 a.m. UTC

To avoid confuision and conflict of usage for RAS related trace event,
add an unified RAS trace event stub.

v5 -> v4: remove explicit RAS menuconfig.
v4 -> v3: change dependency rule of RAS_TRACE.
v3 -> v2: fix dependency in Kconfig.
v2 -> v1: adjust Kconfig to take RAS as a separate subsystem.
