support SE05X integration without extra changes in LmP.

Special Cases
-------------

1. For Factories created **before v85**, it is also necessary to add ``se05x`` to the ``lmp-factory-image`` build:

``recipes-samples/images/lmp-factory-image.bb``:

.. prompt:: text

# Support for SE05X
require ${@bb.utils.contains('MACHINE_FEATURES', 'se05x', 'recipes-samples/images/lmp-feature-se05x.inc', '', d)}

2. If working with a different i.MX machine without default SE05X LmP support (``imx6ullevk`` and ``imx8mm-lpddr4-evk``),
also provide which SoC I2C bus connects to the SE05X device:

``recipes-security/optee/optee-os-fio_%.bbappend``:

.. prompt:: text

EXTRA_OEMAKE:append:<machine> = " \
${@bb.utils.contains('MACHINE_FEATURES', 'se05x', 'CFG_IMX_I2C=y CFG_CORE_SE05X_I2C_BUS=<i2c_bus>', '', d)} \
"

Make sure to push the changes to the ``meta-subscriber-overrides`` repo, triggering a build with the new configurations.
