uart_A is used for the Bluetooth module so with mainline Linux it will
not get a /dev/ttyAMLx character device
For that reason we are not adding an alias for uart_A when a new
board.dts is added

I suggest that you also drop this alias here because it is not visible
to the user ever
Same applies to VIM1 and VIM2 as well


Best regards,
