b315dac3e8 i.MX legacy board file changes for 4.9:
It includes a patch series that moves registrations and initializations
 of all peripherals which are GPIO line consumers for all legacy boards
 from .init_machine to .init_late init level. This is needed to
 proactively prevent boot time issues on the legacy boards due to the
 deprioritized init level of the GPIO controller driver (set lower than
 IOMUX controller driver init level), which is shared among all i.MX
 SoCs.

i.MX6SX has bypass PMIC ready function, as this function
is normally NOT enabled on the board design, so we need
to bypass the PMIC ready pin check during DSM mode resume
flow, otherwise, the internal DSM resume logic will be
waiting for this signal to be ready forever and cause
resume fail.

547e8f5269 ARM: imx: add cpuidle support for i.mx6ul
This patch enables cpuidle driver for i.MX6UL, it
reuses i.MX6SX's cpuidle driver, 3 levels of cpuidle
supported:

1. ARM WFI;
2. SOC in WAIT mode;
3. SOC in WAIT mode + ARM power off.

As i.MX6UL has cortex-A7 CORE with an internal L2
cache, so flushing it before powering down ARM platform
is necessary, flush_cache_all() in last step of cpu_suspend
has very small overhead, just call it to avoid cache
type check for different platforms.

Using the macro makes the code more readable by helping abstract away some

cfee6b5874 ARM: imx6ul: populates platform device at .init_machine
At imx6ul_init_machine, it calls imx6ul_pm_init which needs to find
platform device for ocram, but the default populate platform device is at
of_platform_default_populate_init, which is located at arch_initcall_sync,
and called later than arch_initcall (.init_machine is located at that).
So below warning message will be showed during boots up:

	imx6q_suspend_init: failed to find ocram device!
	imx6_pm_common_init: No DDR LPM support with suspend -19!

Due to lack of ocram device, the suspend mode "mem" which needs ocram to
store suspend routine code is invalid.

This commit populates platform device before imx6ul_pm_init like other
imx6 platforms do, and the suspend mode "mem" can work successfully.

Most peripherals on the i.MX51 have an Off-Platform Peripheral Access
Control Register (OPACR) in which the access rights (together with the
MPROT registers) can be declared.
However, this does not seem to work for example for SSI1+SDMA, because the
supervisor bit is not set for the SDMA unit.
A similar problem was described in the patch for i.MX53 CPU
(ARM: i.MX53: globally disable supervisor protect), and the same solution
is applicable for i.MX51 CPU.
Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).

The mxc_cpu_type and cpu_is_mx() logic is largely unused, and the
few remaining users were easy to convert into simpler code. Now that
they are gone, we can remove all those macros as well.

The related cpu_is_imx6*() set of function unfortunately is harder
to remove, so those are staying around for now.
