[edk2-devel] [RESEND PATCH v3 3/4] OvmfPkg/PlatformBootManagerLib: use PcdAcpiS3Enable to detect S3 support

[Lin, Gary (HPS OE-Linux)]

To avoid the potential inconsistency between PcdAcpiS3Enable and
QemuFwCfgS3Enabled(), this commit modifies PlatformBootManagerLib to
detect S3 support by PcdAcpiS3Enable as modules in MdeModulePkg do.
