Ilias Apalodimas d69759aec2 tpm: measure DTB in PCR1 instead of PCR0 
The PC client spec [0], doesn't describe measurements for DTBs. It does
describe what do to for ACPI tables though.

There is a description for ACPI in 3.3.4.1 PCR[0] – SRTM, POST BIOS,
and Embedded Drivers and they explicitly mention ACPI in there. There's
no mention of ACPI in 3.3.4.2 PCR[1] – Host Platform Configuration.

However, in Figure 6 --  PCR Mapping of UEFI Components ACPI is shown
in PCR1. The general description also mentions PCR0 is for code and PCR1
is for data such as ACPI and SMBIOS.

So let's switch over the DTB measurements to PCR1 which seems a better
fit.
