In case the Device Tree blob passed by the boot agent supplies both an 'interrupts-extended' and an 'interrupts' property in order to allow for older kernels to be usable, prefer the new-style 'interrupts-extended' property which conveys a lot more information. This allows us to have bootloaders willingly maintaining backwards compatibility with older kernels without entirely deprecating the 'interrupts' property. Update the bindings documentation to describe a situation where both the 'interrupts-extended' and the 'interrupts' property are present, and which one takes precedence over the other.

The standard interrupts property in device tree can only handle interrupts coming from a single interrupt parent. If a device is wired to multiple interrupt controllers, then it needs to be attached to a node with an interrupt-map property to demux the interrupt specifiers which is confusing. It would be a lot easier if there was a form of the interrupts property that allows for a separate interrupt phandle for each interrupt specifier. This patch does exactly that by creating a new interrupts-extended property which reuses the phandle+arguments pattern used by GPIOs and other core bindings.

In order to use a device as interrupt controller, it needs to be marked with the DT interrupt-controller property. This commit adds rudimentary documentation about the required standard properties and describes the most commonly used interrupt specifiers.
