This patch adds a inline dummy implementations of_find_matching_node()
in "#ifdef CONFIG_OF" else part. Without this patch,build system can
lead to issues. This was discovered during randconfig testing,in which
ARM_CCI was enabled w/o CONFIG_OF being enabled,leading to the following error:

CC      drivers/bus/arm-cci.o
drivers/bus/arm-cci.c: In function ‘cci_probe’:
drivers/bus/arm-cci.c:971:2: error: implicit declaration of function
‘of_find_matching_node’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[2]: *** [drivers/bus/arm-cci.o] Error 1
make[1]: *** [drivers/bus] Error 2
make: *** [drivers] Error 2
