For the non-DT case, the mct_init() function requires access
to a couple of platform specific constants, but cannot include
the header files in case we are building for multiplatform.
This changes the interface to the platform so we pass all
the necessary data as arguments to mct_init.

The new common clock drivers for exynos are using compile
time constants and soc_is_exynos* macros to provide backwards
compatibility for pre-DT systems, which is not possible with
multiplatform kernels. This moves all the necessary
information back into platform code and removes the mach/*
header inclusions.

There is currently no alternative implementation for of_irq_count
when the function is not defined, and the declaration is hidden,
so this works around calling an undeclared function. It should
really not be needed.

This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.
The multiplatform variant has a number of limitations at the moment:
* It only supports DT-enabled machines. This is not a problem in
the long run, as non-DT machines for exynos are going away.
The main problem here is that the gpio code and the exynos_eint
irqchip are not multiplatform capable but still required for
ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
multiplatform.
The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.

Nothing outside of the rtc driver includes plat/regs-rtc.h,
so we can simply move the file into the same directory,
which allows us to build the file as platform-independent
code.

Nothing uses the NAND register definitions other than the

In multiplatform configurations, we cannot include headers
provided by only the exynos platform. Fortunately a number
of drivers that include those headers do not actually need
them, so we can just remove the inclusions.

plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c
driver, so it can become a local file there and all other
inclusions removed.
plat/sdhci.h is used only to define the platform devices,
and with the exception of the platform_data structure not
needed by the driver, so we can split out the platform_data
definition instead and leave the rest to platform code.

For a DT-only build we don't want to compile devs.c, but we do need

The move is necessary to support early debug output on exynos
with multiplatform configurations. This implies also moving the
plat/debug-macro.S file, but we are leaving the remaining users of that
file in place, to avoid adding large numbers of extra configuration
options to Kconfig.debug

When we enable CONFIG_SPARSE_IRQ, we have to set the value of NR_IRQS in
the machine_desc for legacy IRQ domains, and any file referring to the
number of interrupts or a specific number must include the mach/irqs.h
header file explicitly.

As a preparation for multiplatform support, this introduces
a new Kconfig symbol to split the ATAGS based EXYNOS platforms
from the DT based ones. Turning off CONFIG_EXYNOS_ATAGS disables
all platforms that are not yet converted to DT, and we can
have code that relies on DT checking for this symbol being
disabled.

This binding is intended to represent the hardware reset signals present
internally in most IC (SoC, FPGA, ...) designs.
It consists of a binding for a reset controller device (provider), and a
pair of properties, "resets" and "reset-names", to link a device node
(consumer) to its reset controller via phandle, similarly to the clock
and interrupt bindings.
The reset controller has all information necessary to reset the consumer
device. That could be provided via device tree, or it could be implemented
in hardware.
The aim is to enable device drivers to request a framework API to issue a
reset simply by providing their struct device pointer as the most common
case.
