agp/intel: Reduce extraneous PCI posting reads during init

commit 44d494417278e49f5b42bd3ded1801b6d2254db8 upstream.

Instead of doing a posting read after each GTT entry update, do a single one
at the end of the writes. This should reduce boot time a tiny amount by
avoiding a lot of extra uncached reads.
