STM32F411: simplify cmsis files for stm32f411
...
Delete some macros from cmsis-file we will never use again.
Also replace magic numbers.
Add missing flag to allow -O0 (using R7 as register)

STM32F411: uff... ADC works. Really? Really!
...
Was a little bit tricky. When using ADC with DMA and infitiy readings, everthing is ok. But we don't need so much readings.
To read only one shot after starting the ADC, we need something more.
Disabling continuous conversion and unset the DMA bit. So conversion is stopped. Else the next conversion could start at any ADC.
For a restart just enable again the DMA bit, the continuous conversion and start the ADC.

We don't need an interrupt for the DMA.
Simply clear and set the DMA-bit for the ADC is sufficient.

STM32F411: implement DMA for ADC
...
Eureka!!!
The STM32 has only one data register for all channels. So I want to use the ADC over DMA.
Issues are: It is not possible to stop the DMA or the ADC without uninit and init the hole parts.
We have more or less one option. Manually start the ADC.
So what we have now. We start the ADC after reading the values from DMA buffer. The ADC now make a conversion of all channels.
We can read also the values because it uses a double buffer mode. With that mode we can read the unused buffer.

This code in ifclock(clock_flag_1s) in clock.c should give a nice,

seconds = 0;
minutes++;

sersendf_P(PSTR("%su:"), minutes);

On ARM we use only the 16 byte hardware buffer for sending and
receiving over the serial line, which is often too short for
debugging messages. This implementation works fine and still
neither blocks nor introduces delays for short messages.
Removed while-loop. Looks like we need some more us than the LPC?!? With +7us
