Add the U-Boot DTS overlay for the Lemans EVK board. Mark the required nodes with bootph-all to make them available in the SPL device tree. This covers the UFS host controller and PHY, GCC and RPMH clock controllers, Apps RSC, UART10 console, and the TLMM GPIO controller. A static memory layout is defined temporarily until the changes to get memory information from SMEM ([1]) gets merged.
