As following methods are not used outside ice_vf_lib,
they can be made static:
ice_vf_rebuild_host_vlan_cfg
ice_vf_rebuild_host_tx_rate_cfg
ice_vf_set_host_trust_cfg
ice_vf_rebuild_host_mac_cfg
ice_vf_rebuild_aggregator_node_cfg
ice_vf_rebuild_host_cfg
ice_set_vf_state_qs_dis
ice_vf_set_initialized
In order to achieve that, the order in which these
were defined was reorganized.

Introduce a new generic helper ice_vf_init_host_cfg which performs common
host configuration initialization tasks that will need to be done for both
Single Root IOV and the new Scalable IOV implementation.

Some of the initialization code for Single Root IOV VFs will need to be
reused when we introduce Scalable IOV. Pull this code out into a new
ice_initialize_vf_entry helper function.

The ice_vf_vsi_release function will be used in a future change to
refactor the .vsi_rebuild function. Move this over to ice_vf_lib.c so
that it can be used there.

Add support for 2 virtchnl msgs:
VIRTCHNL_OP_SET_RSS_HENA
VIRTCHNL_OP_GET_RSS_HENA_CAPS
The first one allows VFs to clear all previously programmed
RSS configuration and customize it. The second one returns
the RSS HENA bits allowed by the hardware.
Introduce ice_err_to_virt_err which converts kernel
specific errors to virtchnl errors.

The ice_check_vf_init function takes both a PF and a VF pointer. Every
caller looks up the PF pointer from the VF structure. Some callers only
use of the PF pointer is call this function. Move the lookup inside
ice_check_vf_init and drop the unnecessary argument.
Cleanup the callers to drop the now unnecessary local variables. In
particular, replace the local PF pointer with a HW structure pointer in
ice_vc_get_vf_res_msg which simplifies a few accesses to the HW
structure in that function.

Now that the reset functions do not rely on Single Root specific
behavior, move the ice_reset_vf, ice_reset_all_vfs, and
ice_vf_rebuild_host_cfg functions and their dependent helper functions
out of ice_sriov.c and into ice_vf_lib.c

Introduce the ice_vf_lib.c file along with the ice_vf_lib.h and
ice_vf_lib_private.h header files.
These files will house the generic VF structures and access functions.
Move struct ice_vf and its dependent definitions into this new header
file.
The ice_vf_lib.c is compiled conditionally on CONFIG_PCI_IOV. Some of
its functionality is required by all driver files. However, some of its
functionality will only be required by other files also conditionally
compiled based on CONFIG_PCI_IOV.
Declaring these functions used only in CONFIG_PCI_IOV files in
ice_vf_lib.h is verbose. This is because we must provide a fallback
implementation for each function in this header since it is included in
files which may not be compiled with CONFIG_PCI_IOV.
Instead, introduce a new ice_vf_lib_private.h header which verifies that
CONFIG_PCI_IOV is enabled. This header is intended to be directly
included in .c files which are CONFIG_PCI_IOV only. Add a #error
indication that will complain if the file ever gets included by another
C file on a kernel with CONFIG_PCI_IOV disabled. Add a comment
indicating the nature of the file and why it is useful.
This makes it so that we can easily define functions exposed from
ice_vf_lib.c into other virtualization files without needing to add
fallback implementations for every single function.
This begins the path to separate out generic code which will be reused
by other virtualization implementations from ice_sriov.h and ice_sriov.c
