Amir Mizinski 5317677db4 tpm: add longer timeout for TPM2_CC_VERIFY_SIGNATURE 
While running a TPM2_CC_VERIFY_SIGNATURE operation with RSA 3072-bit
keys the TPM driver fails with the following error:

"kernel: [ 2416.187522] tpm tpm0: Operation Timed out"

Since the TPM PC Client specification does not specify a number for
verify signature operation timeout, and the duration of
TPM2_CC_VERIFY_SIGNATURE with RSA 3072-bit keys exceeds the current timeout
of TPM_LONG (2 seconds), it is preferable to pick the longest timeout
possible.

Therefore, set the duration for TPM2_CC_VERIFY_SIGNATUE to TPM_LONG_LONG
(5 minutes).

[jarkko@kernel.org: mangled the short summary a bit]

README 

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.
