On Armada8k boards various peripherals (e.g. USB) have interrupt lines
connected to on of the ICU interrupt controllers.
After an interrupt is detected it triggers MSI to a given address,
with a programmed value. This in turn triggers an SPI interrupt.
Normally MSI vector should be allocated by ICUs parent and set
during interrupt allocation.
Instead of doing that we relied on the ICU being pre-configured in firmware.
This worked with EDK2 and older versions of U-Boot, but in the newer
ones that is no longer the case.
Extend ICU msi-parents - GICP and SEI to support MSI interface
and use it during interrupt allocation.
This allows us to boot on Armada 7k/8k SoCs independent from the
firmware configuration and successfully use modern U-Boot + device tree.
For SATA interrupts we need to apply a WA previously done in firmware.
We have two SATA ports connected to one controller.
Each ports gets its own interrupt, but only one of them is
described in dts, also ahci_generic driver expects only one irq too.
Fix it by mapping both interrupts to the same MSI when one of them
is allocated, which allows us to use both SATA ports.

in simple multifunction driver.
- follow interrupt changes in DT. Split old ICU driver to function oriented
parts and add drivers for newly defined parts (system error interrupts).
- Many drivers are children of simple multifunction driver. But after r349596
simple MF driver doesn't longer exports memory resources, and all children
must use syscon interface to access their registers. Adapt affected
drivers to this fact.

The fdt node for this driver is a simple-mfd and syscon compatible one
meaning that simplemfd will be the driver attached for it. The gpio driver
is attached to the 'gpio' subnode so use syscon_get_handle_default to
obtain the handle of the syscon from the parent device and use this
to read/write to the memory region.

Since r349596 the syscon driver will map the memory. Since the gpio/pinctrl
controller wants it too set it to SHAREABLE.
This fix the gpio controller for attaching and so consumer can use it.
Now the sdhci_xenon driver can detect presence of an sdcard and attach
