[DistroKit] [PATCH v3 6/8] v7a: stm32mp: add TF-A recipe for STM32MP13

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We have two ways of doing multi-image builds with TF-A:

  - STM32MP15-specific: Multiple device trees can be supplied and TF-A
    is built once and linked with each DT in turn. This was contributed
    to TF-A for DistroKit purposes, but ST broke the compatibility for
    STM32MP13, which requires to be built separately.

  - PTXdist-specific: The PTXdist rule can built multiple platforms in
    different build directories. This requires however that the options
    used are the same, except for platform. We unfortunately need to
    change the option between our two TF-A build though.

Therefore, let's duplicate the upstream TF-A rule for the STM32MP13 and
configure it for use with OP-TEE.
