Refactor mlx5_create_auto_grouped_flow_table() to use ft_attr param
which already carries the max_fte, prio and flags memebers, and is
used the same in similar mlx5_create_flow_table() function.

For vlan push action, if eswitch flow source capability is enabled, flow
source value compared with MLX5_VPORT_UPLINK enum, to determine uplink
port. This lead to syndrome in dmesg if try to add vlan push action.
For example:
$ tc filter add dev vxlan0 ingress protocol ip prio 1 flower \
enc_dst_port 4789 \
action tunnel_key unset pipe \
action vlan push id 20 pipe \
action mirred egress redirect dev ens1f0_0
$ dmesg
...

Use the correct enum value MLX5_FLOW_CONTEXT_FLOW_SOURCE_UPLINK.

Termination tables are used for vlan push actions on uplink ports.
To support RoCE dual port the source port value was placed in a register.
Fix the code to use an API method returning the source port according to
the FW capabilities.

Putting an empty 'mlx5_flow_spec' structure on the stack is a bit
wasteful and causes a warning on 32-bit architectures when building
with clang -fsanitize-coverage:
drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads_termtbl.c: In function 'mlx5_eswitch_termtbl_create':
drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads_termtbl.c:90:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Since the structure is never written to, we can statically allocate
it to avoid the stack usage. To be on the safe side, mark all
subsequent function arguments that we pass it into as 'const'
as well.

HW does not support push VLAN action in the RX direction (packets
arriving from the wire). The FW works around this limitation by haripining
the packet. The hairpin workaround applies only when the push VLAN action
is specified in a termination table, assuring that there are no actions
following the haripin.
Instantiate termination table for push VLAN actions. Re-use identical
terminating tables for increased HW cache efficiency.
