fw_cfg: factor out initialization of FW_CFG_ID (rev. number)
The fw_cfg documentation says this of the revision key (0x0001, FW_CFG_ID):
> A 32-bit little-endian unsigned int, this item is used as an interface
> revision number, and is currently set to 1 by all QEMU architectures
> which expose a fw_cfg device.
arm/virt doesn't. It could be argued that that's an error in
"hw/arm/virt.c"; on the other hand, all of the other fw_cfg providing
boards set the interface version to 1 manually, despite the device
coming from the same, shared implementation. Therefore, instead of
adding
fw_cfg_add_i32(fw_cfg, FW_CFG_ID, 1);
to arm/virt, consolidate all such existing calls in the fw_cfg
initialization code.
