disp: msm: dp: split host init and deinit

create late initialization and early de-initialization.
Call host init/deinit on physical connect/disconnect only
As attention messages from sink doesn't change the physical
cable configurations, call only late init/early deinit in
this case to avoid unnecessary hardware resources
re-initialization.
