Fix the following sparse warning:

drivers/clk/mxs/clk-imx23.c:102:12: warning: symbol 'mx23_clocks_init' was not declared. Should it be static?

It removes the use of mach level IO accessor __mxs_setl/clrl, and hence
removes mach header inclusion from clock driver.

Instead of using the static definitions, get clkctrl and digctl base
addresses with mapping from device tree.

Use macro on variable is not nice, but it's done here to save huge
pointless diff stat.

Change call clk_get_sys() to of_clk_get() to look up timrot clock from
device tree, so that the clk_register_clkdev() call for timrot can be
saved in clock driver.

Select CLKSRC_OF and use clocksource_of_init() to initialize timer, so
that the call to mxs_timer_init() in clock driver can be removed.

It really becomes a maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.

Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx23 client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.

Rather than using the static timer irq definition, we should retrieve
timer irq from device tree for better.

The struct clk_lookup are marked as __initdata, resulting in being
removed from memory after the kernel finished booting. However this
leads to a NULL pointer de-ref if loading a module which uses clk_get.

This patch removes the __initdata from the struct clk_lookup.

The register HW_SSP_VERSION is broken for ssp version detection,
as the address of the register is different between imx23 and imx28.
Let's use platform_device_id to detect the device, so that the use
of cpu_is_xxx can be removed.

Rewrite mxs_dma_is_apbh and mxs_dma_is_apbx in order to support
other SoCs like imx6q and reform the platform_device_id for the
better further dt support.
