[PATCH 1/8] bus: arm-cci: make use of of_find_matching_node_and_match

Instead of the of_find_matching_node()/of_match_node() pair, which requires two
iterations through the match table, make use of of_find_matching_node_and_match(),
which only iterates through the table once.

This also has the side effect of fixing the following following error hit
during randconfig testing:

drivers/bus/arm-cci.c: In function ‘cci_probe’:
drivers/bus/arm-cci.c:976:49: warning: dereferencing ‘void *’ pointer [enabled by default]
cci_config = of_match_node(arm_cci_matches, np)->data;
^
drivers/bus/arm-cci.c:976:49: error: request for member ‘data’ in something not a structure or union
