intel: add bit macro includes where needed

[ Upstream commit 3314f2097dee43defc20554f961a8b17f4787e2d ]

This series is introducing the use of FIELD_GET and FIELD_PREP which
requires bitfield.h to be included. Fix all the includes in this one
change, and rearrange includes into alphabetical order to ease
readability and future maintenance.

virtchnl.h and it's usage was modified to have it's own includes as it
should. This required including bits.h for virtchnl.h.

i40e: Remove circular header dependencies and fix headers

[ Upstream commit 56df345917c09ffc00b7834f88990a7a7c338b5c ]

Similarly as for ice driver [1] there are also circular header
dependencies in i40e driver:
i40e.h -> i40e_virtchnl_pf.h -> i40e.h

Another issue is that i40e header files does not contain their own
dependencies on other header files (both private and standard) so their
inclusion in .c file require to add these deps in certain order to
that .c file to make it compilable.

Fix both issues by removal the mentioned circular dependency, by filling
i40e headers with their dependencies so they can be placed anywhere in
a source code. Additionally remove bunch of includes from i40e.h super
header file that are not necessary and include i40e.h only in .c files
that really require it.

As such changes often also change variable orders, a cleanup

some lines are also reformatted where applicable.

i40e: Add hardware configuration for software based DCB

Add registers and definitions required for applying

Add functions responsible for calculating and setting proper
hardware configuration values for software based DCB functionality.

Add function responsible for invoking Admin Queue command, which
results in applying new DCB configuration to the hardware.

Update copyright dates as appropriate.

Software based DCB is a brand-new feature in i40e driver.
Before, DCB was implemented by Firmware LLDP agent only. The agent was
responsible for handling incoming DCB-related LLDP frames and
applying received DCB configuration to hardware.

New communication channel between software and hardware is required
for software driver. It must be able to calculate and configure all
the registers related for DCB feature.
