imx6q_pm_enter calls imx6sl_set_wait_clk when run on an imx6sl
based machine. However if support for imx6sl is not enabled
at compile time, this prevents us from building the kernel and
we get this link error instead:
arch/arm/mach-imx/built-in.o: In function `imx6q_pm_enter':
:(.text+0x4b84): undefined reference to `imx6sl_set_wait_clk'
This makes the cpu_is_imx6sl function conditionally return false
if imx6sl is disabled at compile-time, which matches what the
older cpu_is_mx* macros did. We have similar inline functions for
the other imx6 variants, but so far I have not run into a case
where the extra #ifdef is necessary.

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

The i.MX6 DualLite/Solo is another i.MX6 family SoC, which is highly
compatible with i.MX6 Quad/Dual. And that's why we choose to support
it using imx6q code with cpu_is_imx6dl() check when necessary.

Only mx508 based board is mach-mx50_rdp and it has been marked as BROKEN
for several releases.
mx508 currently lacks clock support.
In case someone needs to add mx508 support back, then the recommended approach
is to use device tree.

It moves a bunch of header files included in hardware.h and itself
from mach-imx/include/mach to mach-imx, and updates users to include
hardware.h rather than mach/hardware.h. The files in mach-imx/devices
will need to include "../hardware.h".
