sf: Clear display configs when hot pluggable display is disconnected
Display configs for external displays are stored in the framework
everytime we receive a hot plug to connect. However, since the
configs are not cleared on disconnect, framework will just assume
that the configs are valid. This does not work for use cases when
you connect/disconnect external displays with different resolutions.
e.g. 1080p to 4K and vice-versa
With this change we clear the display configs and repopulate when
we receive a hot plug to connect.
