drivers: clk: Adjust temp var data type to properly match that of struct clk_ops
In commit 5c5992cb90cf ("clk: Add debugging for return values"), a
temporary storage variable was added around the ops->get_rate() call
inside clk_get_rate(), so that the result could be passed through
log_ret.
This temporary variable was declared as an int, yet when we look in
struct clk_ops, we can see this needs to be a ulong:
ulong (*get_rate)(struct clk *clk);
This was resulting in a signed to unsigned casting error on our
builds, where a clock value of 0xABCDABCD was being incorrectly cast
to 0xFFFFFFFFABCDABCD.
