The PCA9450 reset configuration can now be performed by the PCA9450 PMIC
driver itself, remove the hard-coded variant from board code and let the
PMIC driver perform this task using one-liner:
```
$ sed -i '/set WDOG_B_CFG to cold reset/,+2 d' $(git grep -l
PCA9450_RESET_CTRL.*0xA1 board/)
```
Venice and i.MX93 EVK required slight manual fix up.
