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.
