[PATCH v14 4/9] fw_cfg: fix sparse warnings with fw_cfg_file

Modify fw_cfg_sysfs_entry to store entry values, instead of reusing the restricted types. Fixes warnings such as: $ make C=1 CF=-D__CHECK_ENDIAN__ drivers/firmware/qemu_fw_cfg.o drivers/firmware/qemu_fw_cfg.c:491:29: warning: incorrect type in assignment (different base types)
