Feature #420: Use standard format of TPM event log
Create Kconfig menu for TPM event log format
New entries should default to one of TCG formats, depending on selected TPM family. Choice of other format shouldn't be restricted. Use of current proprietary format should be explicitly selected by boards that depend on it.
Additionally, config menu should allow to choose at compilation time the hashing algorithms that are to be used. This would allow for limiting size of code for cases with restricted available space.
