Excessive default value causes crash on hardware: x86 baytrail E3845
It is unclear where the data is being populated being 'BLOBLISTT_TCPA_LOG'
is not found elsewhere in the u-boot tree. This leads to confusion about
how much space for TPM log is actually needed.
This was tested on hardware using TPMv1.
