PCR numbers are naturally unsigned values. Further, they are
32 bits, even on 64-bit machines. This change eliminates the
need for negative value and overflow tests.
The parameter name is changed from j and idx to pcr_handle, which is
more descriptive and is similar to the parameter name used in the TPM
2.0 specification.

This patch makes it possible to use the Intel TSS2 for getting
PCR values from the SHA1/SHA256 banks on a TPM2.
It is somewhat naive as it doesn't use the multi-PCR selection
that TSS2 is capable of, that is for a future patch.
