Add new i.MX 8M Mini/Plus SKUs to ConfigBlock handling:
0058: Verdin iMX8M Plus Quad 4GB Wi-Fi / BT IT
0059: Verdin iMX8M Mini Quad 2GB IT
0060: Verdin iMX8M Mini DualLite 1GB WB IT
0061: Verdin iMX8M Plus Quad 2GB
Rename existing SKU (use correct one):
Verdin iMX8M Nano SoloLite 1GB -> Verdin iMX8M Nano Quad 1GB Wi-Fi

The I2C address is 0x25, not 0x35. This according to the datasheet and
tests with a PCA9450A.

The used PMIC has been changed from RHOM BD71837 to NXP PCA9450A.
Adjust the device tree accordingly.
Remove the old ADC node as the ADC has been changed and has no longer
a separate power rail.

V1.1A HW switched the PMIC from BD71837 to PCA9450.
- Disable combined DVS in PCA9450_BUCK123_DVS.
- Increase DDR Voltage to 0.95V as we use a 1.5GHz RAM.
- Configure WDOG_B behaviour.

And Igor, don't forget to drop:
# CONFIG_CMD_IMPORTENV is not set
And add:
CONFIG_OF_LIBFDT_OVERLAY=y
That way our regular distro boot scripts will work out-of-the-box. Thanks!
BTW: With such series a cover letter aka [PATCH 0/0] might make sense. Good old? patman can do all of that and
more...
