From: Chang, Abner @ 2023-05-13 12:33 UTC (permalink / raw)
  To: devel; +Cc: Isaac Oram, Abdul Lateef Attar, Nickle Wang, Tinh Nguyen

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

IpmiFrb is cloned from
edk2-platforms/Features/Intel/OutOfBandManagement/
IpmiFeaturePkg/Frb 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/Frb
until the reference to this instance are removed from
platforms.
