SODIMM_174 and SODIMM_250 gpio lines are used as, respectively,
WIFI_W_WKUP_HOST and WIFI_WKUP_WLAN, and hence should be not
used for user purposes. Remove these gpio line names from WiFi
variant.

This is needed due to the GPIO also going to the AzureWave module
Power Down signal. Change also the regulator-name to reflect for
what it is really used.

In newest hardware revisions we are no longer able to switch the
voltage +V3.3_Wi-Fi that powers the AzureWave module.

cap-power-off-card means according to documentation "Powering off the
card is safe." which we know from latest investigations is not true.
Plus in newest hardware revisions this is also not possible so remove
this.

This reworks the dtsi files to allow to also build device trees for
Verdin iMX8MM V1.1 hardware.
The module level device tree for V1.1 HW is imx8mm-verdin-v1.1.dtsi,
for V1.0 HW the imx8mm-verdin.dtsi is reworked to include the V1.1 dtsi
and then it deletes and adds whatever is different.
This commit incorporates the following HW changes:
- Changed PMIC
- Removal of ADC MAX11607 (The replacement TI TLA2024 is not yet added)
- Removal of external PCIe PHY Clock in favour of SoC provided one
- Prepare for not stuffed security alternatives SE050, ATTPM20P
- Changed pin usage, see below
Pin usage changed from V1.0 to V1.1 HW:
To ease creation of V1.0 and V1.1 device trees move all pin groups,
also wifi and nonwifi ones, into imx8mm-verdin-v1.1.dtsi and change
them as needed in imx8mm-verdin.dtsi for V1.0 HW.
The eMMC reset is now connected to the SD1_RESET_B ball.
Add it to the eMMC pin groups for V1.1.
CTRL_FORCE_OFF_MOCI# used to be controlled by SAI5_RXC in V1.0 HW. In V1.1
HW it is no longer under SW control.
Delete the unused pin group for V1.1.
Wi-Fi_WKUP_WLAN used to be controlled by SD1_RESET_B in V1.0 HW. In V1.1
HW it is controlled by SAI5_RXC.
Update the pin group for V1.1.

This commit holds the initial devicetrees for verdin-imx8mm module.
They are based on the devicetree from toradex_4.14-2.3.x-imx branch
and contain only a stripped down subset of the features which compile
and should act as a starting point for further bringup on this
branch.
