Subject: [PATCH 5.14 254/432] dpaa2-switch: do not enable the DPSW at probe time

From: Ioana Ciornei <ioana.ciornei@....com>

[ Upstream commit 042ad90ca7ce70f35dc5efd5b2043d2f8aceb12a ]

We should not enable the switch interfaces at probe time since this is
trigged by the open callback. Remove the call dpsw_enable() which does
exactly this.
