Helge Deller fd37a5c699 parisc: Fix argument pointer in real64_call_asm()
commit 6e3220ba3323a2c24be834aebf5d6e9f89d0993f upstream.

Fix the argument pointer (ap) to point to real-mode memory
instead of virtual memory.

It's interesting that this issue hasn't shown up earlier, as this could
have happened with any 64-bit PDC ROM code.

I just noticed it because I suddenly faced a HPMC while trying to execute
the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI
text console.
