crypto: octeontx2 - add devlink option to set t106 mode

On CN10KA B0/CN10KB, CPT scatter gather format has modified
to support multi-seg in inline IPsec. Due to this CPT requires
new firmware and doesn't work with CN10KA0/A1 firmware. To make
HW works in backward compatibility mode or works with CN10KA0/A1
firmware, a bit(T106_MODE) is introduced in HW CSR.

This patch adds devlink parameter for configuring T106_MODE.
This patch also documents the devlink parameter under
Documentation/crypto/device_drivers.

net: devlink: let the core report the driver name instead of the drivers

The driver name is available in device_driver::name. Right now,
drivers still have to report this piece of information themselves in
their devlink_ops::info_get callback function.

In order to factorize code, make devlink_nl_info_fill() add the driver
name attribute.

Now that the core sets the driver name attribute, drivers are not
supposed to call devlink_info_driver_name_put() anymore. Remove
devlink_info_driver_name_put() and clean-up all the drivers using this
function in their callback.
