soc/amd/cezanne: Update GPP clk req code to use ARRAY_SIZE 

Currently the GPP clk req configuration code assumes that the size of
the config array is `GPP_CLK_OUTPUT_COUNT`. This commit changes that
code to use the `ARRAY_SIZE` macro instead.

BRANCH=guybrush
BUG=b:250009974
TEST=Ran on nipperkin device, verified that clk req settings are
correct.
