From ba774b89b5a206c71a2ce0db8184747fac0f6af7 Mon Sep 17 00:00:00 2001
From: Paolo Bonzini <pbonzini@redhat.com>

Subject: [PATCH 2/3] OvmfPkg: create a separate PlatformDebugLibIoPort
instance for SEC
The next patch will want to add a global variable to
PlatformDebugLibIoPort, but this is not suitable for the SEC
phase, because SEC runs from read-only flash. The solution is
to have two library instances, one for SEC and another
for all other firmware phases. This patch adds the "plumbing"
for the SEC library instance, separating the INF files and
moving the constructor to a separate C source file.
