  To: devel; +Cc: Isaac Oram, Abdul Lateef Attar, Nickle Wang, Tinh Nguyen

From: Abner Chang <abner.chang@amd.com>

IpmiBmcElog is cloned from
edk2-platforms/Features/Intel/OutOfBandManagement/
IpmiFeaturePkg/BmcElog in order to consolidate
edk2 system manageability support in one place.
Uncustify is applied to C files and no functionalities
are changed in this patch.

We will still keep the one under IpmiFeaturePkg/BmcElog
until the reference to this instance are removed from
platforms.
