tpmdd updates for Linux v5.1

From: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com>

Clean up the transmission flow
==============================

Cleaned up the whole transmission flow. Locking of the chip is now done in
the level of tpm_try_get_ops() and tpm_put_ops() instead taking the chip
lock inside tpm_transmit(). The nested calls inside tpm_transmit(), used
with the resource manager, have been refactored out.

Should make easier to perform more complex transactions with the TPM
without making the subsystem a bigger mess (e.g. encrypted channel patches
by James Bottomley).

PPI 1.3 support
===============

TPM PPI 1.3 introduces an additional optional command parameter that may be
needed for some commands. Display the parameter if the command requires
such a parameter. Only command 23 (SetPCRBanks) needs one.

The PPI request file will show output like this then:

   # echo "23 16" > request
   # cat request
   23 16

   # echo "5" > request
   # cat request
   5

Extend all PCR banks in IMA
===========================

Instead of static PCR banks array, the array of available PCR banks is now
allocated dynamically. The digests sizes are determined dynamically using a
probe PCR read without relying crypto's static list of hash algorithms.

This should finally make sealing of measurements in IMA safe and secure.

TPM 2.0 selftests
=================

Added a test suite to tools/testing/selftests/tpm2 previously outside of
the kernel tree: https://github.com/jsakkine-intel/tpm2-scripts.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
