The Secure Launch MLE environment uses PCRs that are only accessible from
the DRTM locality 2. By default the TPM drivers always initialize the
locality to 0. When a Secure Launch is in progress, initialize the
locality to 2.

Changes in v2:
- Modified 32b entry code to prevent causing relocations in the compressed
kernel.
- Dropped patches for compressed kernel TPM PCR e
e and allow it to be pulled into the
setup kernel in the same manner as sha256 is.

Prior to running the next kernel via kexec, the Secure Launch code
closes down private SMX resources and does an SEXIT. This allows the
next kernel to start normally without any issues starting the APs etc.
