imx_set_soc_revision() and imx_get_soc_revision() to maintain

Most DT ARM machs require common clock providers initialized before timers.
Currently, arch/arm machs use .init_time to call of_clk_init right before
clocksource_of_init. This prevents to remove that callback and use the default
one instead.

This patch adds a call to of_clk_init() to the default .init_time callback
for COMMON_CLK enabled machs to allow to remove custom callbacks where applicable.
While at it, also reorder includes alphabetically.

Current vt8500 board init calls of_clk_init() from vtwm_clk_init. To allow
consolidation of DT driven .time_init, move of_clock_init() to a temporary
.time_init callback that will be removed when arch-wide callback is available.
With previous pmc_base parsing helper for vt8500 clock providers, we can also
safely remove the call to vtwm_clk_init() and get rid of some includes.

Commit cdc58d60 "cpufreq: imx6q-cpufreq:
remove device tree parsing for cpu nodes" assumed the pdev->dev is set to
cpu0 device in the platform code. But it actually points to the virtual
cpufreq-cpu0 platform device which is not present in the device tree.
Most of the information needed by cpufreq is stored in cpu0 DT node.
So cpu_dev must point to cpu0 device.

This patch fixes the wrong assignment to cpu_dev.
