Subject: [net-next 13/15] net/mlx5: Move esw multiport devlink param to eswitch code

From: Saeed Mahameed <[email-masked]>
Date: Fri, 9 Jun 2023 18:42:52 -0700

From: Shay Drory <[email-masked]>

Move the param registration and handling code into the eswitch
code as they are related to each other. No point in having the
devlink param registration done in separate file.
