Add following peripherals support for the Emtop i.MX8M Mini Baseboard
* Wi-Fi
* Audio
* SD card
* RTC
* CAN bus
* USB OTG
Signed-off-by: Tarang Raval <tarang.raval@siliconsignals.io>
---
Changes in v2:
1. Updated the node name and pinctrl name.
2. Removed the 'regulators' container.
3. Removed a stray blank line.
4. Removed non-existent properties.
5. Removed unused node and pinctrl:
-modem-reset
-pinctrl_uart1
6. Defined the CAN transceiver reset GPIO separately.
Change in v3:
1. Removed 'can-connector'.
2. Use USB connector instead of extcon_usb.
3. Changed id-gpio to id-gpios.
4. Use Level trigger IRQ in the CAN node.
5. Corrected the compatible property of RTC.
6. Added blank lines to separate the pinctrl groups.
Changes in v4:
1. Sorted I2C device nodes by slave address.
2. Moved properties above the "status" property in the Wi-Fi node.
Change in v5:
1. I mistakenly removed <pinctrl-canbus>; it has now been re-added.
2. Added Author name

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments.
