remove no longer used memory_region_allocate_system_memory()

Browse Source 
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().
