msm: camera: cpas: Add support to turn on optional clks

Browse Source 
This change is needed for domain id feature support.

When a PHY and its lanes for a particular CSID are
protected in a secure session, the same for other
unused CSIDs are to be protected as well. This is
to prevent other CSIDs from tapping the data streaming
onto those lanes if they share the same PHY.

For this, the clocks for other CSIDs (eg CSID-Lite)
need to be turned on. Given that the existing driver
turns on the clocks for the CSID in use, and that
this clock information is embedded within the CSID
hw blocks, these clocks are now exposed as optional
clocks to CPAS to enable the PHY driver to turn them
on during streamon for secure session.
