ARM: cns3xxx: Fix build with CONFIG_PCI=y

commit 726ed10bf211ae9b83f5982aec0f8d8af53ebdf2 ("ARM: 6269/1: Add 'code'
parameter for hook_fault_code()") breaks CNS3xxx build:

  CC      arch/arm/mach-cns3xxx/pcie.o
pcie.c: In function 'cns3xxx_pcie_init':
pcie.c:373: warning: passing argument 4 of 'hook_fault_code' makes integer from pointer without a cast
pcie.c:373: error: too few arguments to function 'hook_fault_code'

This commit fixes the small issue.
