dpaa2-switch: add ENDPOINT_CHANGED to the irq_mask
Commit 84cba72956fd ("dpaa2-switch: integrate the MAC endpoint support")
added support for MAC endpoints in the dpaa2-switch driver but omitted
to add the ENDPOINT_CHANGED irq to the list of interrupt sources. Fix
this by extending the list of events which can raise an interrupt by
extending the mask passed to the dpsw_set_irq_mask() firmware API.
There is no user visible impact even without this patch since whenever a
switch interface is connected/disconnected from an endpoint both events
are set (LINK_CHANGED and ENDPOINT_CHANGED) and, luckily, the
LINK_CHANGED event could actually raise the interrupt and thus get the
MAC/PHY SW configuration started.
Even with this, it's better to just not rely on undocumented firmware
behavior which can change.
