This is a very initial pm support and basically does nothing.
With this pm support entry, drivers can start testing their own
pm functions.

_CLK_SET_RATE does not only handle the cpu clock but also other
clocks, so do not hardcode the HW_CLKCTRL_CPU register.

reg | (1 << clk->enable_shift) always evaluates to true. Switch it
to & which makes much more sense

Since commit
6d803ba (ARM: 6483/1: arm & sh: factorised duplicated clkdev.c)
platforms need to select CLKDEV_LOOKUP instead of COMMON_CLKDEV and need
to include <linux/clkdev.h>.

The mxs duart is actually an amba-pl011 device. This commit changes
the duart device code to dynamically allocate amba-pl011 device,
so that drivers/serial/amba-pl011.c can be used on mxs.

There are 2 versions of the timrot on Freescale MXS-based SoCs.
The v1 on MX23 only gets 16 bits counter, while v2 on MX28
extends the counter to 32 bits.
The implementation uses two timers, one for clock_event and
another for clocksource. MX28 uses timrot 0 and 1, while MX23
uses 0 and 2.
