U-Boot builds can have different device tree filenames than Linux because, for example, stm32mp15-based DHCOM devices use a single dts file like stm32mp15xx-dhcom-pdk2 for all different flavors.
Thats why commit 0509e68cdf68 introduced STM32MP1_DTS_U_BOOT. Sadly commit 4b263e2f4c3a reverted the usage for the U-Boot build.
So make use of STM32MP1_DTS_U_BOOT again for the U-Boot build.
