Change the format of the S_CRTM_VERSION string to ucs-2 since this
is what seems to be commonly used by other firmwares following
insight from a TCG work group member.

This patch adds TPM 2.0 support along with the firmware API that Linux
uses to transfer the firmware log.
The firmware API follows the "PFW Virtual TPM Driver" specification.
The API has callers in existing Linux code (prom_init.c) from TPM 1.2
times but the API also works for TPM 2.0 without modifications.
The TPM 2.0 support logs PCR extensions of measurements of code and data.
For this part we follow the TCG specification "TCG PC Client
Platform Firmware Profile Specification" (section "Event Logging").
Other relevant specs for the construction of TPM commands are:
- Trusted Platform Module Library; Part 2 Structures
- Trusted Platform Module Library; Part 3 Commands

The following patch adds a SHA256 implementation based on the algorithm
description in NIST FIPS PUB 180-4. The patch includes test cases that test
the sha256 implementation and pass on big and little endian ppc64 hosts.

This patch adds a TPM driver for the CRQ interface as used by
the QEMU PAPR implementation.
Also add a Readme that explains the benefits and installation procedure
for the vTPM.
