[Qemu-ppc] [PATCH v2 08/18] hw/nvram/fw_cfg: Move fw_cfg_file_slots_allocate() to common_realize()

[Philippe Mathieu-Daudé]

Each implementation (I/O and MEM) calls fw_cfg_file_slots_allocate()
then fw_cfg_common_realize().
Simplify by moving the fw_cfg_file_slots_allocate() call into
fw_cfg_common_realize() where it belongs.
