vboot2: Introduce vb2ex_hwcrypto API
This patch extends the vboot2 API by three callback functions that the
platform firmware may implement to offer hardware crypto engine support.
For now we only support this for hash algorithms, and we will only allow
it for firmware body hashes (not the keyblock or preamble which are too
small to matter execution-time-wise anyway). The API is similar to the
vb2api_*_hash() functions used to start body hashing in the first place,
but we still take this round trip through vboot to allow it to do
key/signature management and retain full control of the verification
process. We also add a new preamble flag to explicitly disable this
feature, so that we can later return to a solely software-based
verification path through a firmware update in case a hardware crypto
engine turns out to be insecure.

vboot2: Move old struct handling to lib20/
This is part 4 of a series of changes to rearrange the vboot2 library
so that it's possible to start using the new-style data structs. This
change moves knowledge of the old vboot1 data structs into lib20; 2lib
now contains only code which is common to both vboot2.x libraries
(that is, code which is data structure version agnostic).
No functional changes; just rearranging code and tests.

vb2: parse dev mode in phase1
The rest of the system software expects dev mode to be
orthogonal to recovery mode. However, vb2_fw_phase1() was
only checking recovery mode. The caller would then not
call vb2_fw_phase2() which checked the developer mode settings.
Fix this by doing the necessary steps in vb2_fw_phase1().

vboot2: Move and rename functions
Move packed key functions to their own file, in preparation for
introducing support for vb2_packed_key2.
Rename the awfully-named vb2_verify_fw_preamble2() function to
vb2_load_fw_premable(), since the new structs actually have a
vb2_fw_preamble2 struct and that would be very confusing.
Rename vb2_verify_fw_keyblock() to vb2_load_fw_keyblock(), so it
matches.
No functional changes, just renaming.

vboot2: use enum hash algorithm
This changes the internals of vboot2 to use the enumerated type for
hash algorithm. The conversion from crypto algorithm is done only
when unpacking the key (and ok, in checking the rsa padding, but that
goes away in the next change). This is preparation for the vboot2
data types, which separate signature and hash algorithms into their
own fields.
There is no external change in the calling API to vboot, and no change
to the external data structures.
