[PATCH 2/7] hw/nvram: Rename FW_CFG_MIPS as generic FW_CFG Kconfig symbol

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Targets using the fw_cfg device might have architecture specific
keys. If so, they define the fw_cfg_arch_key_name() function.

The use of FW_CFG_MIPS is not MIPS-specific, it is simply the
architectural implementation. Rename it using the generic 'FW_CFG'
and move the Kconfig declaration in hw/nvram/ where fw_cfg code
is maintained.
