Add CX9020 board based on mx53loco.
Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse
serial_mxc with DTE and prepare for device tree migration of other
functions and imx53 devices.

The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- CCAT FPGA connected to emi
- enable rtc

There two iomuxc for i.MX6SLL. One is normal IOMUXC, the other
is for IOMUXC_SNVS.

Add a DM port of Marvell pin control driver.
The A8K SoC family contains several silicone dies interconnected
in a single package. Every die is normally equipped with its own
pin controller unit.
There are 2 pin controllers in A70x0 SoC and 3 in A80x0 SoC.

Commit b02e4044ff8e ("libfdt: Bring in upstream stringlist
functions") broke codying style in some places especially
by inserting an extra whitespace before fdt_stringlist_count().

Marek reports warnings in UniPhier pinctrl drivers when compiled by
GCC 6.x, like:

  drivers/pinctrl/uniphier/pinctrl-uniphier-ld20.c:58:18: warning:
  'usb3_muxvals' defined but not used [-Wunused-const-variable=]
   static const int usb3_muxvals[] = {0, 0};
                    ^~~~~~~~~~~~

My intention here is to compile minimum set of pin data for SPL to
save memory footprint, but GCC these days is clever enough to notice
unused data arrays.

We can fix it by sprinkling around __maybe_unused on those arrays,
but I did not do that because they are counterparts of the pinctrl
drivers in Linux.  All the pin data were just copy-pasted from Linux
and are kept in sync for maintainability.

I chose a bit tricky way to fix the issue; calculate ARRAY_SIZE of
*_pins and *_muxvals and set their sum to an unused struct member.
This trick will satisfy GCC because the data arrays are used anyway,
but such data arrays will be dropped from the final binary because
the pointers to them are not used.

These have now landed upstream. The naming is different and in one case the
function signature has changed. Update the code to match.

This applies the following upstream commits by
Thierry Reding <treding@nvidia.com> :

   604e61e fdt: Add functions to retrieve strings
   8702bd1 fdt: Add a function to get the index of a string

There two iomuxc for i.MX6ULL. one iomuxc is compatible is i.MX6UL,
the other iomuxc is for SVNS usage, similar with the one in mx7.
