Nilaan Gunabalachandran 711eabbf43 disp: msm: sde: account for pref lm when exposing avail resources ...

If an external display, such as DP, requests for the available
resources, resource manager (RM) will provide a count of all unused
mixers. If the primary/secondary display(s) are not active, the RM
will report the associated preferred mixers as free resources.
However, RM will not allow preferred mixers to be allocated to other
displays. DP driver could look at these available resources and assume
a high resolution mode is possible and fail during resource allocation.

This change updates the available resources info API to account for
primary/secondary preferences while exposing available resources.
