* [PATCH] SecurityPkg: Fix GetSupportedAndActivePcrs counter calculation

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2855
The Tpm2GetCapabilitySupportedAndActivePcrs function prints a
count number that should reflect the *supported and currently
active* PCR banks, but the implementation in place displays
instead the count of the *supported PCR banks* retrieved
directly from the Tpm2GetCapabilityPcrs()
TPML_PCR_SELECTION output.

The counter should only take into account those PCRs banks
which are active.

Replaced usage of EFI_D_* for DEBUG_* definitions in debug
messages.

Hi Bodrigo
I have seen a patch with similar title and content earlier. May I know which one the latest one?

Please add *PATCH-V2* in the title to tell us which one is the latest version, and always add V3/V4/V5 to future update.
I will review and give comment to the latest version.

Thank you
Yao Jiewen

Hi Jiewen,

Sorry about that, I was debugging my git SMTP configuration and I might have send the same patch twice at some point.
This is the version of the patch that should be reviewed:

  >Subject: [PATCH] SecurityPkg: Fix GetSupportedAndActivePcrs counter calculation
  >Date: Mon, 20 Jul 2020 15:27:13 -0700

FYI, I also sent another patch to be reviewed, which is independent and not to be confused with this one.

Good to know.
Usually, if I saw second patch, I will override the first patch. 

It brings confusing in this case, because I notice that there is NO signed-off or Cc in the second one. It seems in invalid patch.
So I will ignore the latest one and just review the old one.

I recommend do test/debug with a test patch, not a real patch, to avoid confusing in the future.

Thank you
Yao Jiewen
