parisc: Handle R_PARISC_PCREL32 relocations in kernel modules

Commit 0de7985 (parisc: Use generic extable search and sort routines)
changed the exception tables to use 32bit relative offsets.

This patch now adds support to the kernel module loader to handle such
R_PARISC_PCREL32 relocations for 32- and 64-bit modules.
