arm-soc: soc specific changes, part 2

Browse Source 
This adds support for the spear13xx platform, which has first been under
 review a long time ago and finally been completed after generic spear
 work has gone into the clock, dt and pinctrl branches.
 
 Also a number of updates for the samsung socs are part of this branch.

Pull arm-soc: soc specific changes (part 2) from Olof Johansson:
 "This adds support for the spear13xx platform, which has first been

  spear work has gone into the clock, dt and pinctrl branches.

  Also a number of updates for the samsung socs are part of this branch."

Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much
worse than they are: the exonys5 init code was refactored in commit
fd454997d6 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and
then commit f10590c983 ("ARM: EXYNOS: add GPC4 bank instance") added a
new gpio chip define and did tiny updates to the init code.

So the conflict diff looks like hell, but it's actually a fairly simple
change.

* Samsung Exynos Interrupt Combiner Controller
Samsung's Exynos4 architecture includes a interrupt combiner controller which
can combine interrupt sources as a group and provide a single interrupt request
for the group. The interrupt request from each group are connected to a parent
interrupt controller, such as GIC in case of Exynos4210.
The interrupt combiner controller consists of multiple combiners. Upto eight
interrupt sources can be connected to a combiner. The combiner outputs one
combined interrupt for its eight interrupt sources. The combined interrupt
is usually connected to a parent interrupt controller.
A single node in the device tree is used to describe the interrupt combiner
controller module (which includes multiple combiners). A combiner in the
interrupt controller module shares config/control registers with other
combiners. For example, a 32-bit interrupt enable/disable config register
can accommodate upto 4 interrupt combiners (with each combiner supporting
upto 8 interrupt sources).
Required properties:
- compatible: should be "samsung,exynos4210-combiner".
- interrupt-controller: Identifies the node as an interrupt controller.
- #interrupt-cells: should be <2>. The meaning of the cells are
* First Cell: Combiner Group Number.
* Second Cell: Interrupt number within the group.
- reg: Base address and size of interrupt combiner registers.
- interrupts: The list of interrupts generated by the combiners which are then
connected to a parent interrupt controller. The format of the interrupt
specifier depends in the interrupt parent controller.
Optional properties:
- samsung,combiner-nr: The number of interrupt combiners supported. If this
property is not specified, the default number of combiners is assumed
to be 16.
- interrupt-parent: pHandle of the parent interrupt controller, if not
inherited from the parent node.
Example:
The following is a an example from the Exynos4210 SoC dtsi file.
combiner:interrupt-controller@10440000 {
compatible = "samsung,exynos4210-combiner";
interrupt-controller;
#interrupt-cells = <2>;
reg = <0x10440000 0x1000>;
interrupts = <0 0 0>, <0 1 0>, <0 2 0>, <0 3 0>,
