[RESEND][PATCH 5/8] PM: EM: Remove old debugfs files and print all 'flags'

[Lukasz Luba]

The Energy Model gets more bits used in 'flags'. Avoid adding another
debugfs file just to print what is the status of a new flag. Simply
remove old debugfs files and add one generic which prints all flags
as a hex value.
