Fix it by using the pdc_result struct instead when calling firmware and copy the return values back into the result struct when finished sucessfully. While debugging this code I noticed that the pdc_type wasn't set correctly either, so let's fix that too.

For a long time, we have had random segmentation faults building packages on machines with PA8800/8900 processors. These machines only support equivalent aliases. We don't see these faults on machines that don't require strict coherency. So, it appears TLB speculation sometimes leads to cache corruption on machines that require coherency. This patch adds TLB flushes to flush_cache_range and flush_cache_mm when coherency is required. We only flush the TLB in flush_cache_page when coherency is required. The patch also optimizes flush_cache_range. It turns out we always have the right context to use flush_user_dcache_range_asm and flush_user_icache_range_asm. The patch has been tested for some time on rp3440, rp3410 and A500-44. It's been boot tested on c8000. No random segmentation faults were observed during testing.

This patch extends this to after the copy.
