powerpc: fix build failure by disabling attribute-alias warning in pci_32
Commit 2479bfc9bc600 ("powerpc: Fix build by disabling attribute-alias
warning for SYSCALL_DEFINEx") forgot arch/powerpc/kernel/pci_32.c
Latest GCC version emit the following warnings
As arch/powerpc code is built with -Werror, this breaks build with
GCC 8.1
This patch inhibits this warning
In file included from arch/powerpc/kernel/pci_32.c:14:
./include/linux/syscalls.h:233:18: error: 'sys_pciconfig_iobase' alias between functions of incompatible types 'long int(long int, long unsigned int, long unsigned int)' and 'long int(long int, long int, long int)' [-Werror=attribute-alias]
asmlinkage long sys##name(__MAP(x,__SC_DECL,__VA_ARGS__)) \
^~~
./include/linux/syscalls.h:222:2: note: in expansion of macro '__SYSCALL_DEFINEx'
__SYSCALL_DEFINEx(x, sname, __VA_ARGS__)
