hv:Replace dynamic memory with static for ptdev

Browse Source 
-- Config MAX_PT_IRQ_ENTRIES 64 in Kconfig
-- Remove ptdev list
-- Add alloc_ptdev_entry_id api

v3-->v4:
  -- move is_entry_active from assign.c to ptdev.h
  -- Add clear active flag in release_entry
v2-->v3:
  -- Remove redundancy active check for ptdev entry
     in release_all_entries and get_ptdev_info
v1-->v2:
  -- split to small patches
