This keeps the numbering of the /sys/class/pwmchipX independent of
which overlays are loaded and allows the use of Verdin PWM_3_DSI from
user space if it is not used as a backlight PWM.

Add aliases for the RTCs. This sets /dev/rtc0 to represent the external
RTC, potentially backuped by a coin cell on the carrier and /dev/rtc1
representing the SoC provided RTC not backuped.

Adds the ADC. The ADC TI TLA2024 is used. Currently there is no specific
driver for the chip and we use the ADS015 which has a compatible
programming model..
The ADS1015 additionally comparator features which are not available in
the TLA2024.

This is used to connect to the on module ADC.

Add a gpio pinmuxing to the i2c nodes which will allows the I2C driver
to recover from stuck communication signals.

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.
