[PATCH V3 0/3] tpm: Add new vTPM device driver for PPC64

[Ashley Lai <adlai@linux.vnet.ibm.com>]

Change log V3:
- Replaced TPM_NO_EVENT_LOG macro with stubs
- Removed tpm_noeventlog.c file 
- Called of_node_put() before return in tpm_of.c

Change log V2:
- Removed unnecessary tpm_bios_log_setup and tpm_bios_log_teardown
  functions in tpm_eventlog.h (patch 3/3).
- Added more descriptions on vTPM (patch 1/3).

These patches add support for IBM vTPM for PPC64. This new device driver
works on firmware that supports vTPM (firmware release 740 or higher).

Tested on Power7+ system with firmware level ZM770_001.
