From: Simon Glass sjg@chromium.org
Align bloblist tags with the FW handoff spec v0.9. The most common ones are from 0. TF related ones are from 0x100. All non-standard ones from 0xfff000.
Added new defined tags: BLOBLISTT_OPTEE_PAGABLE_PART for TF. BLOBLISTT_TPM_EVLOG and BLOBLISTT_TPM_CRB_BASE for TPM.
