Tsung Ho Wu 804a0433e0 drivers/pc80/tpm: add support for TPM emulator SwTPM 2.0 module

Add software TPM 2.0 emulator to tpm device probe list.
SwTPM: https://github.com/stefanberger/swtpm

Tested on qemu q35 with MAINBOARD_HAS_LPC_TPM and MAINBOARD_HAS_TPM2
set in qemu-q35 Kconfig.
Qemu: see qemu flags at
https://s3hh.wordpress.com/2018/06/03/tpm-2-0-in-qemu/

How to see it work.
Ubuntu 18.04:
1. Install SwTPM from https://github.com/stefanberger/swtpm

2. Add MAINBOARD_HAS_LPC_TPM and MAINBOARD_HAS_TPM2 to
src/mainboard/emulation/qemu-q35/Kconfig and rebuild
coreboot.rom

3. mkdir -p swtpm0

4. swtpm socket --tpmstate dir=swtpm0 --tpm2 --ctrl \
type=unixio,path=swtpm0/swtpm-sock --log level=20 &

5. qemu-system-x86_64 -machine q35 -m 2G \
-chardev socket,id=chrtpm,path=swtpm0/swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm -device \
tpm-tis,tpmdev=tpm0 -pflash build/coreboot.rom \
-serial $(tty) -display none

6. Check boot log and search 'Found TPM'.
