The series makes some house-keeping tasks on i40e driver:
Patch 1: Removes unnecessary back pointer from i40e_hw
Patch 2: Moves I40E_MASK macro to i40e_register.h where is used
Patch 3: Refactors I40E_MDIO_CLAUSE* to use the common macro
Patch 4: Add header dependencies to <linux/avf/virtchnl.h>
Patch 5: Removes circular header deps, fixes and cleans headers
Patch 6: Moves DDP specific macros and structs to i40e_ddp.c
Patch 7: Moves mem alloc structures to i40e_alloc.h
Patch 8: Splits i40e_osdep.h to i40e_debug.h and i40e_io.h
Patch 9: Simplifies memory alloction functions

2.41.0
The macro is practically used only in i40e_register.h header file except
few I40E_MDIO_CLAUSE* macros that are defined in i40e_type.h
Move I40E_MASK macro to i40e_register.h header, I40E_MDIO_CLAUSE* macros
are refactored in subsequent patch.

2.41.0
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
depenencies 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.

The macros I40E_MDIO_CLAUSE22* and I40E_MDIO_CLAUSE45* are using I40E_MASK
together with the same values I40E_GLGEN_MSCA_STCODE_SHIFT and
I40E_GLGEN_MSCA_OPCODE_SHIFT to define masks.
Introduce I40E_GLGEN_MSCA_OPCODE_MASK and I40E_GLGEN_MSCA_STCODE_MASK
for both shifts in i40e_register.h and use them to refactor the macros
mentioned above.

2.41.0
The .back field placed in i40e_hw is used to get pointer to i40e_pf
instance but it is not necessary as the i40e_hw is a part of i40e_pf
and containerof macro can be used to obtain the pointer to i40e_pf.
Remove .back field from i40e_hw structure, introduce i40e_hw_to_pf()
and i40e_hw_to_dev() helpers and use them.
