Abhijit Kulkarni 1ef5cee6ca disp: msm: add api to get active status of hw blocks ...

This change introduces new ctl path api read_active_status to check
if a particular hw block is active or not in the current control path.
This is specially required in continuous splash use case when bootloader
has programmed certain blocks and the kernel driver tries to find
out the same configuration. This is used to ascertain which DSC block
is active in continuous splash case since DSC blocks are not tied to
mixer blocks.
