This adds the infrastructure to support older firmware APIs.
The API version number is stored as part of the filename, we first try to
load the most recent firmware and progressively try lower versions.
The API version is also read from the firmware self and stored as part
of the iwl_priv structure. Only firmware that is supported by driver will
be loaded. The version number read from firmware is compared
to supported versions in the driver not the API version used as part of
filename.
An example using this new infrastrucure:
if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
Driver interacts with Firmware API version >= 2.
} else {
Driver interacts with Firmware API version 1.
