For imx6ull none-emmc device trees enable:
- MXT TS over adapter or connector (board dependent);
- ad7879 support;
- Parallel RGB/VGA capability.

NXP and AzureWave don't recommend using SDIO bus mode 3.3V@50MHz due
to noise affecting the wireless throughput. Colibri iMX6ULL uses only
3.3V signaling for Wi-Fi module AW-CM276NF.
Limit the SDIO Clock on Colibri iMX6ULL to 25MHz.

Move all atmel and fusion touchscreen nodes from board-level
to the main module DT. Prepare the DTs for
use with atmel mxt overlays, adding required pinmux groups.
The common scheme of pin groups for TS overlays:
- pinctrl_atmel_conn - SODIMM 106/107 pins for INT/RST (default)
- pinctrl_atmel_adap - SODIMM 28/30 pins for INT/RST signals.

Add GPIO line names on module level. Those are all GPIOs which a user
might use on his custom carrier board. If more meaningful names are
available on the carrier board, the user can overwrite the line names
in the carrier board level device tree.

The driver mwifiex_sdio stucks after the wifi firmware crash.
Enabling asynchronous interrupts processing in sdio driver
fixes this issue and allows the mwifiex_sdio driver to be reloaded
and continue operates successfully.
Works better with the driver from the backported-5.4 package.

In 4.14 devicetress are based on the mainline DT's and only necessary
stuff for downstream is put into those devicetrees.
This commit holds the changes for imx6ull*colibri* from 4.9.

Add the pinmuxing and a inactive node for flexcan1 on SODIMM 55/63
and move the inactive flexcan modes to imx6ull-colibri-eval-v3.dtsi
where they belong.
Note that this commit does not enable flexcan functionality, but rather
eases the effort needed to do so.

Boards based on imx6ul have duplicate memory nodes:
- One coming from the board dts file: memory@
- One coming from the imx6ul.dtsi file.
Fix the duplication by removing the memory node from the dtsi file
and by adding 'device_type = "memory";' in the board dts.

i.MX6ULL has different operating ranges than i.MX6UL so add the
operating points for the i.MX6ULL and remove them from board device
trees. A 25mV offset is added to the minimum allowed values like for the
i.MX6UL.
The valid frequencies are now selected by the cpufreq driver according
to ratings stored in fuses since commit 0aa9abd4c212 ("cpufreq: imx6q:
check speed grades for i.MX6ULL")

Pass the memory unit-adress to fix the following build warnings with W=1:
Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name
There are cases where dts passes an empty memory node, which will be filled
by the bootloader. Passing the memory base address still allows the
bootloader to fill the memory size.

Add support for the Computer on Module Colibri iMX6ULL and its
Bluetooth/Wifi variant along with the development/evaluation carrier
board device trees. Follow the usual hierarchic include model,
maintaining shared configuration in imx6ull-colibri.dtsi and
imx6ull-colibri-eval-v3.dtsi respectively.
