The PCR algorithms used for vboot are frequently causing confusion (e.g.
see CB:35645) because depending on the circumstances sometimes a
(zero-extended) SHA1 value is interpreted as a SHA256, and sometimes a
SHA256 is interpreted as a SHA1. We can't really "fix" anything here
because the resulting digests are hardcoded in many generations of
Chromebooks, but we can document and isolate it better to reduce
confusion. This patch adds an explanatory comment and fixes both
algorithms and size passed into the lower-level TPM APIs to their actual
values (whereas it previously still relied on the TPM 1.2 TSS not
checking the algorithm type, and the TPM 2.0 TSS only using the size
value for the TCPA log and not the actual TPM operation).

Adds a "sd_media" boot_device to allow booting from the SD card. This
assumes that the generated "MLO" file is placed at a 128KB offset from
the start of the SD card, to allow for the MBR etc. to be at the start
of the SD card. Placing the MLO file here allows the AM335x boot ROM to
load and execute the bootblock stage as well, as 128KB is one of the
offsets the boot ROM checks when looking for the next stage to execute.
As part of this, a FMD for the Beaglebone has also been defined. It's
sized at 32M somewhat arbitrarily, as SD cards could allow for much
bigger payloads.
TEST: Beaglebone boots from bootblock into romstage. Romstage to
ramstage still doesn't work as it needs RAM initialization first.
