msm: mdss: ioctl to get pp feature version

Some of the PP(post processing) features in MDP might be upgraded when
new revision hardware is released. Clients of driver were relying on
MDP revision to decide which version of the PP feature is supported.
With MDP revision approach the client of driver needs to maintain a
mapping between MDP revision and PP feature version. This change
exposes ioctl to driver clients to query PP driver version of feature
instead of maintaining mapping.
