ice: Enable switching default Tx scheduler topology
Introduce support for Tx scheduler topology change, based on user
selection, from default 9-layer to 5-layer.
Change requires NVM (version 3.20 or newer) and DDP package (OS Package
1.3.30 or newer - available for over a year in linux-firmware, since
commit aed71f296637 in linux-firmware ("ice: Update package to 1.3.30.0"))
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=aed71f296637
Enable 5-layer topology switch in init path of the driver. To accomplish
that upload of the DDP package needs to be delayed, until change in Tx
topology is finished. To trigger the Tx change user selection should be
changed in NVM using devlink. Then the platform should be rebooted.
