Subject: [PATCH V1 07/13] selftests/resctrl: Don't use variable argument list for setup function
struct resctrl_val_param has setup() function that accepts variable
argument list. But, presently, all the test cases use only 1 argument as
input and it's struct resctrl_val_param *. So, instead of variable argument
list, directly pass struct resctrl_val_param * as parameter.
