Add a new function, clkdm_in_hwsup(), that returns true if a clockdomain is configured for hardware-supervised idle. It does not actually read the hardware; rather, it checks an internal flag in the struct clockdomain, which is changed when the clockdomain is switched in and out of hardware-supervised idle. This should be safe, since all changes to the idle mode should pass through the clockdomain code. Based on a set of patches by Rajendra Nayak <rnayak@ti.com> which do the same thing by checking the hardware bits. This approach should be faster and more compact.
