cpufreq: armada-8k: Fix parameter type warning

gclement · vireshk · commit 0990319a0400 · 2023-12-18T11:22:57.000+05:30
The second parameter of clk_get() is of type 'const char *', so use
NULL instead of the integer 0 to resolve a sparse warning:

drivers/cpufreq/armada-8k-cpufreq.c:60:40: warning: Using plain integer as NULL pointer
drivers/cpufreq/armada-8k-cpufreq.c:168:40: warning: Using plain integer as NULL pointer
