[PATCH net-next V2 03/13] net/mlx5: E-Switch, move devcom init from TC to eswitch layer

[Tariq Toukan <tariqt@nvidia.com>]

From: Shay Drory <shayd@nvidia.com>

Move the E-swtich devcom component management from TC layer to ESW
layer.

This refactoring places devcom lifecycle management at the appropriate
layer and prepares for SD LAG which needs devcom registration
independent of the TC/representor initialization.
