clocksource/drivers/dw_apb_timer_of: Fix probe failure

The driver refuses to probe with -EINVAL since the commit 5d9814d
("clocksource/drivers/dw_apb_timer_of: Add error handling if no clock
available").

Before the driver used to probe successfully if either "clock-freq" or
"clock-frequency" properties has been specified in the device tree.

That commit changed

if (A && B)
	panic("No clock nor clock-frequency property");

into

if (!A && !B)
	return 0;

That's a bug: the reverse of `A && B` is '!A || !B', not '!A && !B'
