Revert "[Chassis][Voq]update to add buffer_queue config on system ports (#12156)" (#13421)

This reverts commit 1cffbc7b07.

Why I did it
This PR reverts the changes done in #12156 in 202205.
The dependant swss changes in PR sonic-net/sonic-swss#2618 are not merged in 202205 yet.

This revert is to avoid issues on 202205 till the sonic-net/sonic-swss#2618 is merged in.

Once sonic-net/sonic-swss#2618 changes are merged, this change will be added back.
