staging: vchiq_core: Drop vchiq_pagelist.h

vchiq_pagelist.h only defines one struct and a couple of macros.
It can be merged with vchiq_core since all the pagelist related
function helpers are now in vchiq_core for bulk transfers.

Move the struct and related macros to vchiq_core header and drop
vchiq_pagelist.h.
