The device tree parsing code for the STM32 platform is using its own FDT helper functions, some of them being rather generic. In particular the existing fdt_read_uint32_array() implementation is now almost identical to the new generic code in fdt_wrappers.c, so we can remove the ST specific version and adjust the existing callers. Compared to the original ST implementation the new version takes a pointer to the DTB as the first argument, and also swaps the order of the number of cells and the pointer.
