I recently ran into a situation where I needed more than 16 stream ids
for an smmu on an AMD SOC, but we are currently limited to 16 by:

#define MAX_MASTER_STREAMIDS        MAX_PHANDLE_ARGS
#define MAX_PHANDLE_ARGS 16

I expect others will run into this in the future as more advanced SOCs
start to come out. The resulting one line patch has been tested to fix
the problem.
