The imx6sl low power mode implementation inherits imx6q/dl one,
and pm-imx6q.c can just work for imx6sl with some minor updates.
Let's enable imx6sl suspend support by reusing pm-imx6q.c and use
cpu_is_imxXX() to handle the those minor differences between imx6sl
and imx6q/dl.

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
  Freescale i.MX
  $ cat /sys/devices/soc0/soc_id
  i.MX6Q
  $ cat /sys/devices/soc0/revision

Add imx6sl support into imx_init_revision_from_anatop(), so that it can
be used to initialize cpu type and revision on imx6sl.

Config iomux-gpr1 to select clock source for fec system clock.
Clear gpr1[14], gpr1[18-17] bit to select the fec clock source
from internal anatop PLL.

With arch/arm calling of_clk_init(NULL) from time_init(), we can now
remove custom .init_time hooks.

The optimized L2 prefect and power setting done in imx_init_l2cache()
can also benefit imx6sl, so let's call the function on imx6sl as well.

Instead of explicitly calling clock initialization functions, we can
declare the functions with CLK_OF_DECLARE() and then call common
of_clk_init() to have them invoked properly.
