[PATCH v4 0/6] TPM 2.0 support

[Jarkko Sakkinen]

This patch set enables TPM2 protocol and provides drivers for FIFO and
CRB interfaces.

Major changes since v1:

- Improved struct tpm_chip life-cycle by taking advantage of devres
  API.
- Refined sysfs attributes as simple key-values thereby not repeating
  mistakes in TPM1 sysfs attributes.
- Documented functions in tpm-chip.c and tpm2-cmd.c.
- Documented sysfs attributes.

Major changes since v2:

- Lots of fixes in calling order in device drivers (thanks to Jason
  Gunthorpe for pointing these out!).
- Attach sysfs attributes to the misc device because it represents
  TPM device to the user space.

Major changes since v3:

- Disable sysfs attibutes for TPM 2.0 for until we can sort out the 
  best approach for them.
- Fixed all the style issues found with checkpatch.pl.
