Normally we don't do this, but enough changes have accumulated that
we're doing a tree-wide one-off update of the name & style.

There is the hardware accelerator for SHA computation inside npcx9. This
CL wraps the Nuvoton SHA library APIs (which are in the ROM) to Chromium
EC's SHA256_* APIs to speed up the SHA256 computation.
With the help of the hardware accelerator, the hash computation runs
several times faster than the software method (see b:155771688 for more
detailed evaluation data.) Also, we can gain ~840 bytes of code size.

TEST=pass "make buildall"
TEST=flash the same RW image; #define/#undef CONFIG_SHA256_HW_ACCELERATE
; verify the RW hash value is the same in the console message.
TEST=with the following test CL, move test patterns in test/sha256.c
to board/npcx9_evb/test_sha256.c; pass all test patterns.

This unifies all the EC header files to use __CROS_EC_FILENAME_H
as the include guard. Well, except for test/ util/ and extra/
which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

This copies the parts of sha256.c that we need from vboot_reference,
and removes the explicit dependency on vboot_reference. That
dependency was a good idea when we were doing full verified boot in
the EC, but is now overkill and makes it harder for others to reuse
the EC code. This also lets us call EC functions directly instead of
needing vboot_stub.cc; that reduces code size by ~100 bytes.
