parisc: Fix HPMC handler by increasing size to multiple of 16 bytes
commit d5654e156bc4d68a87bbaa6d7e020baceddf6e68 upstream.
Make sure that the HPMC (High Priority Machine Check) handler is 16-byte
aligned and that it's length in the IVT is a multiple of 16 bytes.
Otherwise PDC may decide not to call the HPMC crash handler.
