Introduce shmobile_init_delay() that gets CPU specific
parameters from DT and sets up the early delay from
there. This allows us to both remove frequency information
from the C code and consolidate existing code.

These changes are mostly for ARM specific device drivers that either
don't have an upstream maintainer, or that had the maintainer ask
us to pick up the changes to avoid conflicts. A large chunk of this
are clock drivers (bcm281xx, exynos, versatile, shmobile), aside from
that, reset controllers for STi as well as a large rework of the
Marvell Orion/EBU watchdog driver are notable.

New and updated SoC support. Among the things new for this release are:
- More support for the AM33xx platforms from TI
- Tegra 124 support, and some updates to older tegra families as well
- imx cleanups and updates across the board
- A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM,
and turned out to be too broad a name. New name is ARCH_BCM_MOBILE.
- A whole bunch of updates and fixes for integrator, making the platform code
more modern and switches over to DT-only booting.
- Support for two new Renesas shmobile chipsets. Next up for them is more work
on consolidation instead of introduction of new non-multiplatform SoCs, we're
all looking forward to that!
- Misc cleanups for older Samsung platforms, some Allwinner updates, etc.

Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"New and updated SoC support. Among the things new for this release
are:
- More support for the AM33xx platforms from TI
- Tegra 124 support, and some updates to older tegra families as well
- imx cleanups and updates across the board
- A rename of Broadcom's Mobile platforms which were introduced as
ARCH_BCM, and turned out to be too broad a name. New name is
ARCH_BCM_MOBILE.
- A whole bunch of updates and fixes for integrator, making the
platform code more modern and switches over to DT-only booting.
- Support for two new Renesas shmobile chipsets. Next up for them is
more work on consolidation instead of introduction of new
non-multiplatform SoCs, we're all looking forward to that!
- Misc cleanups for older Samsung platforms, some Allwinner updates,
etc"

Tie in the APMU SMP code on r8a7791. When used together
with the secondary CPU device node and smp_ops in the
board specific code then this will allow use of the
two Cortex-A15 cores in the r8a7791 SoC.

r8a7779 INTC needs IRL pin mode settings to determine
behavior of IRQ0 - IRQ3, and r8a7779_init_irq_extpin()
is controlling it via irlm parameter.
But this function registers renesas_intc_irqpin driver
if irlm was set, and this value depends on platform.
This is not good for DT.
This patch splits r8a7779_init_irq_extpin() function
into "mode settings" and "funtion register" parts
