MP1 update

This PR:

• Fix issue with ADC (in both mode: engineering or production)
• Small cleanup
• Update the README according to @FCHSTM
  [New variant] STM32MP157_DK  #717 (comment)

I will probably also update the generated script name with the sketch name.
@kbumsik as discussed in stm32duino/Arduino_Tools#47 (comment), do you think it is correct to use sed in the generate part of the script? Done

Maybe I will add the MP1 Cube update 1.1.1:

• HAL and CMIS device not changed
• OpenAMP updated to v1.0.3

Yes. I tested it.

should work, tested in Linux and Windows.

Well,
I guess this PR could be merged when CI build will be ended.

I just spotted some while I read through the rendered README.md. It should be fine for me otherwise.
