EXYNOS SOC series use MCT for kernel timer and MCT has two types of
clock event timers, which are mct-comp and mct-tick.
Because the clock rate of each event timer is diffent from the other,
this patch fixes cycles_per_jiffy for each timer's periodic mode.

Following the merge of CPU PM notifiers and L2 resume code, this patch

Add entries to clocks_off for some additional clocks which are not
currently used by any mainline drivers. They default on at power up
but are never actually used so
If these blocks are actually supported some of these bindings would need
to be redone properly, for example hooking up to the muxes that use them,
but that can be done incrementally.

Add a very basic cpuidle driver for S3C64xx which merely drives the CPU
into IDLE mode. We could do this with pm_idle but the more modern idiom
is to use cpuidle and the intention is to go further and support STOP
and DEEP-STOP states in conjunction with the pm_domain framework.
The actual state entry code was lifted from Tomasz Figa's work on spica.

Amba core assumes the pclk to be named as apb_pclk. During device probe,
it tries to get that clock and enable that. When PM_RUNTIME is enabled,
dma clock is not explicitly enabled in pl330_probe, which causes device
probe to fail. Adding a clkdev entry for apb_pclk for mdma1 fixes the
problem.
