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.
