[PATCH 2/7 v3] trace, AER: Move trace into unified interface

["Chen, Gong" <gong.chen@linux.intel.com>]

AER uses a separate trace interface by now. To make it
consistent, move it into unified RAS trace interface.

v3 -> v2: change dependency rule of RAS_TRACE.
v2 -> v1: remove unnecessary dependency in drivers/ras/Kconfig.

Signed-off-by: Chen, Gong <gong.chen@linux.intel.com>
