The encryption of the U-Boot environment uses the HWID as key
modifier. The HWID was being read using the fsl_otp driver sysfs
entries and over two words. The driver is now deprecated and also
the cc8x and cc8m platforms have different number of HWID words.
This patch modifies the function that reads the HWID words by
using new entries on the device tree 'digi,hwid_X' where X is the
index of the HWID word.
It also removes the need to select CONFIG_MD5 which is already
auto-selected on sandbox_defconfig by other config switches.

Update u-boot-fw-utils patches to apply on current upstream version. Remove
recipe for version 2017.09 since both U-Boot v2017.03 and v2018.03 work fine
with the newer version.

Patches added in 'meta-swupdate' (backported from U-Boot) broke our
layer. We also had those patches, so remove them and make sure the
rest or our patches are applied after the ones from 'meta-swupdate'
by using an anonymous python function instead of appending to the
SRC_URI variable.

The caam encryption check was only done from fw_env_write and fw_env_read
functions, which are not called when using the functions exported as a library.
Move the check_caam_encryption() call to fw_env_open(), which is called from
all code paths. A similar check for AES encryption cannot be moved because it
requires the AES key as an argument.

This patch adds the functionality to automatically detect if the enviroment
is encrypted (through the device tree). If it is, the environment is encrypted
and decrypted as required in a transparent way for the user.
