net/mlx5: Relocate function declarations from port.h to mlx5_core.h

The port header is a general file under include, yet it
contains declarations for functions that are either not
exported or exported but not used outside the mlx5_core
driver.

To enhance code organization, we move these declarations
to mlx5_core.h, where they are more appropriately scoped.

This refactor removes unnecessary exported symbols and
prevents unexported functions from being inadvertently
referenced outside of the mlx5_core driver.

And while the mlx5i_get_port_settings is the same as
mlx5_query_port_oper therefore let's remove it.

According to the IB spec link_width_oper and ib_proto_oper should be u16
and not as written u8, so perform casting as a preparation to cross-RDMA
patch which will fix that type for all drivers in the RDMA subsystem.

net/mlx5e: Fix GRE key by controlling port tunnel entropy calculation

Flow entropy is calculated on the inner packet headers and used for
flow distribution in processing, routing etc. For GRE-type
encapsulations the entropy value is placed in the eight LSB of the key
field in the GRE header as defined in NVGRE RFC 7637. For UDP based
encapsulations the entropy value is placed in the source port of the
UDP header.
The hardware may support entropy calculation specifically for GRE and
for all tunneling protocols. With commit df2ef3bff193 ("net/mlx5e: Add
GRE protocol offloading") GRE is offloaded, but the hardware is
configured by default to calculate flow entropy so packets transmitted
on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN),
GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the
hardware behaviour must be controlled by the driver.

Ensure port entropy calculation is enabled for offloaded VXLAN tunnels
and disable port entropy calculation in the presence of offloaded GRE
tunnels by monitoring the presence of entropy enabling tunnels (i.e
VXLAN) and entropy disabing tunnels (i.e GRE).
