[PATCH] tpm: more bios log parsing fixes

From: Seiji Munetoh <seiji.munetoh@gmail.com>

Change the binary output format to actual ACPI TCPA log structure since the
current format does not contain all event-data information that need to
verify the PCRs in TPM.  tpm_binary_bios_measurements_show() uses
get_event_name() to convert the binary event-data to ascii format, and puts
them as binary.  However, to verify the PCRs, the event-data must be a
actual binary event-data used by SHA1 calc.  in BIOS.

So, I think actual ACPI TCPA log is good for this binary output format.
That way, any userland tools easily parse this data with reference to TCG
PC specification.
