OMAP2/3 clock: Extend find_idlest() to pass back idle state value
Current implementation defines clock idle state indicators based on the cpu information (cpu_is_omap24xx() or cpu_is_omap34xx()) in a system wide manner. This patch extends the find_idlest() function in clkops to pass back the idle state indicator for that clock, thus allowing idle state indicators to be defined on a per clock basis if required. This is specifically needed on AM35xx devices as the new IPSS clocks indicates the idle status (0 is idle, 1 is ready) in a way just opposite to how its handled in OMAP3 (0 is ready, 1 is idle).
