fw_cfg_mem: flip ctl_mem_ops and data_mem_ops to DEVICE_BIG_ENDIAN
The standalone selector port (fw_cfg_ctl_mem_ops) is only used by big
endian guests to date (*), hence this change doesn't regress them. Paolo
and Alex have suggested / requested an explicit DEVICE_BIG_ENDIAN setting
here, for clarity.
(*) git grep -l fw_cfg_init_mem
hw/nvram/fw_cfg.c
hw/ppc/mac_newworld.c
hw/ppc/mac_oldworld.c
hw/sparc/sun4m.c
include/hw/nvram/fw_cfg.h
The standalone data port (fw_cfg_data_mem_ops) has max_access_size 1 (for
now), hence changing its endianness doesn't change behavior for existing
guest code.
