agp/uninorth: Fix oops caused by flushing too much
This fixes a sporadic oops at boot on G5 Power Macs. The table_end
variable has the address of the last byte of the table. Adding on
PAGE_SIZE means we flush too much, and if the page after the table
is not mapped for any reason, the kernel will oops. Instead we add
on 1 because flush_dcache_range() interprets its second argument as
the first byte past the range to be flushed.
