For performance reasons there is a need to have support for selectable
Tx scheduler topology. Currently firmware supports only the default
9-layer and 5-layer topology. This patch series enables switch from
default to 5-layer topology, if user decides to opt-in.

---
v4:
- restored the initial way of passing firmware data to ice_cfg_tx_topo
  function in ice_init_tx_topology function in ice_main.c file. In v2
  and v3 version it was passed as const u8 parameter which caused kernel
  crash. Because of this change I decided to drop all Reviewed-by tags.

v3:
- fixed documentation warnings

v2:
- updated documentation
- reorder of variables list (default-init first)
- comments changed to be more descriptive
- added elseif's instead of few if's
- returned error when ice_request_fw fails
- ice_cfg_tx_topo() changed to take const u8 as parameter (get rid of copy
  buffer)
- renamed all "balance" occurences to the new one
- prevent fail of ice_aq_read_nvm() function
- unified variables names (int err instead of int status in few
  functions)
- some smaller fixes, typo fixes
