clk: fix count parameter type for clk_release_all

The second parameter for clk_release_all is used as an unsigned
(which makes sense) but the function prototype declares it as an int.
This causes warnings/error like such below:

include/clk.h:422:48: error: conversion to ‘int’ from ‘unsigned int’ may change the sign of the result [-Werror=sign-conversion]
  422 |         return clk_release_all(bulk->clks, bulk->count);

To fix this, changed the type of the count to `unsigned int`
