parisc: Fix module loading error with JUMP_LABEL feature 

Commit 62217beb39 ("parisc: Add static branch and JUMP_LABEL feature") missed
to add code to handle PCREL64 relocations which are generated when creating a
jump label on a 64-bit kernel.

This patch fixes module load errors like this one:
# modprobe -v ipv6
insmod /lib/modules/5.2.0-rc1-JeR/kernel/net/ipv6/ipv6.ko
modprobe: ERROR: could not insert 'ipv6': Exec format error
dmesg reports:
module ipv6: Unknown relocation: 72
