feat(stm32mp15-fdts): add Avenger96 board with STM32MP157A DHCOR SoM
This should replace the stm32mp157a-avenger96.dts with the new device
tree files split into the STM32MP15 DHCOR SoM definition and the
Avenger96 baseboard like it's done in Linux and U-Boot.
Differences to stm32mp157a-avenger96.dts:
- Enable sdmmc2 for booting from eMMC
- improved clock settings like in U-Boot commit b6055945
"ARM: dts: stm32: Adjust PLL4 settings on AV96 again"
- improved DDR settings for DHSOMs like in U-Boot commit 92ca0f74
"ARM: dts: stm32: Synchronize DDR setttings on DH SoMs"
TF-A with this new dts(i) files on this board was fully tested with
the latest OP-TEE developer setup.
