Ninad Palsule 139fdb3ed8 tpm: Add support for TPM device over I2C bus 
Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices. I2C model only supports
TPM2 protocol.

This commit includes changes for the common code.
- Added I2C emulation model. Logic was added in the model to temporarily
  cache the data as I2C interface works per byte basis.
- New tpm type "tpm-tis-i2c" added for I2C support. The user has to
  provide this string on command line.

Testing:
  TPM I2C device module is tested using SWTPM (software based TPM
  package). Qemu uses the rainier machine and is connected to swtpm over
  the socket interface.

  The command to start swtpm is as follows:
  $ swtpm socket --tpmstate dir=/tmp/mytpm1    \
                 --ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock  \
                 --tpm2 --log level=100

  The command to start qemu is as follows:
  $ qemu-system-arm -M rainier-bmc -nographic \
            -kernel ${IMAGEPATH}/fitImage-linux.bin \
            -dtb ${IMAGEPATH}/aspeed-bmc-ibm-rainier.dtb \
            -initrd ${IMAGEPATH}/obmc-phosphor-initramfs.rootfs.cpio.xz \
            -drive file=${IMAGEPATH}/obmc-phosphor-image.rootfs.wic.qcow2,if=sd,index=2 \
            -net nic -net user,hostfwd=:127.0.0.1:2222-:22,hostfwd=:127.0.0.1:2443-:443 \
            -chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \
            -tpmdev emulator,id=tpm0,chardev=chrtpm \
            -device tpm-tis-i2c,tpmdev=tpm0,bus=aspeed.i2c.bus.12,address=0x2e
