openrisc: fix PTRS_PER_PGD define
On OpenRISC, with its 8k pages, PAGE_SHIFT is defined to be 13. That makes the expression (1UL << (PAGE_SHIFT-2)) evaluate to 2048. The correct value for PTRS_PER_PGD should be 256. Correcting the PTRS_PER_PGD define unveiled a bug in map_ram(), where PTRS_PER_PGD was used when the intent was to iterate over a set of page table entries. This patch corrects that issue as well.
