The i.MX6 has two general-purpose LVDS clocks that can be driven
from a variety of sources.  This patch adds a mux and a gate for
both of these clocks.

The patch enables soc bus infrastructure and adds a function
imx_soc_device_init() to report soc info via soc device interface for
imx6qdl and imx6sl.  With the support, user space can get soc related
info by looking at sysfs like below.

  $ cat /sys/devices/soc0/machine
  Freescale i.MX6 Quad SABRE Smart Device Board
  $ cat /sys/devices/soc0/family

The patch creates a common function imx_init_revision_from_anatop() by

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.

With previous pmc_base parsing helper for vt8500 clock providers, we can also

Currently, clock providers for vt8500 depend on machine_init providing
pmc_base address before calling of_clk_init. With upcoming arch-wide

that gets called if there is no pmc_base set, yet.
