[PATCH 11/18] hw/nvram/fw_cfg: Remove FWCfgState::file_slots field

[Philippe Mathieu-Daudé]

The FWCfgState::file_slots integer was only set in the
hw_compat_2_8[] array, via the 'x-file-slots=0x10' property.
We removed all machines using that array, lets remove that
property and all the code around it. The number of slots is
always FW_CFG_FILE_SLOTS_DFLT (32).
