IMX6 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the fact that the GPC block is actually the first
interrupt controller in the chain, kernels with this patch
applied wont have any suspend-resume facility when booted
with old DTs, and old kernels with updated DTs won't even boot.

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts.  However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected.  This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board.  It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.

The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral.  Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.

This reverts commit b1d27c79.

Previously we switched the SSI scriprt to dual-fifo mode to reduce playback
underrun issue, which is only included by SDMA firmware version 2. However,
there are quite a lot people still using version 1 or default firmware in
the ROM code of SoC while these two kinds of firmwares do not support the
dual-fifo script and the audio function on their platform would be broken.

Thus this patch provisionally reverts the dual-fifo script to the original
single fifo script to meet all kinds of users' requirements, including the
version 1/2 or inner ROM firmware.
