EV_HPD_INIT_SETUP flag is used to trigger the initialization of external

Lets get rid of it.
And another question. Between patches #2 and #3 we have both
INIT_SETUP event and the PM doing dp_display_host_init(). Will it work
correctly?
yes, i had added if (!dp->core_initialized) into dp_display_host_init().
should I merge this patch into patch #2?
