[PATCH v5 72/79] remove no longer used memory_region_allocate_system_memory()

[Igor Mammedov <imammedo@redhat.com>]

all boards were switched to using memdev backend for main RAM,
so we can drop no longer used memory_region_allocate_system_memory()

-/**
- * memory_region_allocate_system_memory - Allocate a board's main memory
- * @mr: the #MemoryRegion to be initialized
- * @owner: the object that tracks the region's reference count
- * @name: name of the memory region
- * @ram_size: size of the region in bytes
- *
- * This function allocates the main memory for a board model, and
- * initializes @mr appropriately. It also arranges for the memory
- * to be migrated (by calling vmstate_register_ram_global()).
- *
- * Memory allocated via this function will be backed with the memory
- * backend the user provided using "-mem-path" or "-numa node,memdev=..."
- * if appropriate; this is typically used to cause host huge pages to be
- * used. This function should therefore be called by a board exactly once,
- * for the primary or largest RAM area it implements.
- *
- * For boards where the major RAM is split into two parts in the memory
- * map, you can deal with this by calling memory_region_allocate_system_memory()
- * once to get a MemoryRegion with enough RAM for both parts, and then
- * creating alias MemoryRegions via memory_region_init_alias() which
- * alias into different parts of the RAM MemoryRegion and can be mapped
- * into the memory map in the appropriate places.
- *
- * Smaller pieces of memory (display RAM, static RAMs, etc) don't need
- * to be backed via the -mem-path memory backend and can simply
- * be created via memory_region_init_ram().
