The memory area of the TPM measurement log is currently not properly
duplicated for carrying it across kexec when an Open Firmware
Devicetree is used. Therefore, the contents of the log get corrupted.
Fix this for the kexec_file_load() syscall by allocating a buffer and
copying the contents of the
Refactor IMA buffer related functions to make them reusable for carrying
TPM logs across kexec.

RISC-V recently added kexec_file() support, which uses enables kexec
IMA. We're the first 32-bit platform to support this, so we found a
build bug.

Simplify tpm_read_log_of() by moving reusable parts of the code into
an inline function that makes it commonly available so it can be
used also for kexec support. Call the new of_tpm_get_sml_parameters()
function from the TPM Open Firmware driver.

The of-tree subsystem does not currently preserve the IBM vTPM 1.2 and
vTPM 2.0 measurement logs across a kexec on PowerVM and PowerKVM. This
series fixes this for the kexec_file_load() syscall using the flattened
device tree (fdt) to carry the TPM measurement log's buffer across kexec.
