The suspend-imx6.S is introduced recently for suspend low-level assembly
code. Since function v7_cpu_resume() is only used by suspend support,
it makes sense to move the function into suspend-imx6.S, and control the
build of the file with CONFIG_SUSPEND option.

For imx50-weim and imx6q-weim type of devices, there might a WEIM CS
space configuration register in General Purpose Register controller,
e.g. IOMUXC_GPR1 on i.MX6Q.
Depending on which configuration of the following 4 is chosen for given
system, IOMUXC_GPR1[11:0] should be set up as 05, 033, 0113 or 01111
correspondingly.
CS0(128M) CS1(0M) CS2(0M) CS3(0M)
CS0(64M) CS1(64M) CS2(0M) CS3(0M)
CS0(64M) CS1(32M) CS2(32M) CS3(0M)
CS0(32M) CS1(32M) CS2(32M) CS3(32M)
The patch creates a function for such type of devices, which scans
'ranges' property of WEIM node and build the GPR value incrementally.
Thus the WEIM CS GPR can be set up automatically at boot time.

Booting a mx6q system built with multi_v7_defconfig leads to the following
error messages on boot:
[ 0.037758] imx6q_ocram_suspend_init: ocram pool unavailable!
[ 0.037768] imx6_pm_common_init: failed to initialize ocram suspend -19!
This happens because CONFIG_SRAM is not selected by default in
multi_v7_defconfig.
Fix this by selecting CONFIG_SRAM at ARCH_MXC level, so that other SoCs could
use the SRAM driver as well.
As SRAM automatically selects GENERIC_ALLOCATOR, just drop it from the Kconfig

ANATOP/CCM or external clock source through pad GPIO_16. But in case
of the external clock source, bit IOMUXC_GPR1[21] needs to be cleared.
The patch adds the support for systems that use an external clock source
and distinguishes above two cases by checking if the PTP clock specified

When system enter suspend, we can set the DDR IO to
high-Z state to save DDR IOs' power consumption, this
operation can save many power(from ~26mA@1.5V to ~15mA@1.5V,
measured on i.MX6Q SabreSD board, R25) of DDR IOs. To
achieve that, we need to copy the suspend code to ocram
and run the low level hardware related code(set DDR IOs
to high-Z state) in ocram.
If there is no ocram space available, then system will
still do suspend in external DDR, hence no DDR IOs will
be set to high-Z.
