SSP0 and SSP1 use ref_io0 which has decreased frequency. Expand
the frequency fix for ref_io1 to get SSP2 and SSP3 to work.

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 definition of clocks ref_io0 and ref_io1 were inverted.  It causes
a mmc regression on some boards right away.  Fix the regression by
correcting the ref_io clock definition.

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.

With old mxs clock support removed, the timer_clk argument of
mxs_timer_init is unused now, so remove it.
