ARM cpufreq updates for 6.8

- Use 'NULL' instead of '0' in Armada cpufreq driver (Gregory CLEMENT).
cpufreq: armada-8k: Fix parameter type warning

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
