[edk2-devel] [Patch 1/2] UefiCpuPkg/RegisterCpuFeaturesLib: Default avoid print.

[Dong, Eric]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1984

Current debug message brings much restriction for the platform
which use this driver.

For PEI and DXE phase, platform mush link base DebugLib (without
using any pei/dxe services, even for its dependent libraries).

This patch default disable this debug message, only open it when
need to debug the related code.
