7693ef3bd6 stmhal: Allow ADC.read_timed to take Timer object in place of freq.
This allows a user-specified Timer for the triggering of the ADC read,
mirroring the new behaviour of DAC.write_timed.

Addresses issue #1129.

abc24c1876 stmhal: Allow DAC.write_timed to take Timer object in place of freq.
This allows the DAC to use a user-specified Timer for the triggering
(instead of the default Timer(6)), while still supporting original
behaviour.

Addresses issues #1129 and #1388.

This fixes #733.

04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

7fdfa93700 stmhal: Add Timer class: simple TIM control, incl callback on IRQ.
Simple but functional timer control.  More sophistication will
eventually be added, or for now just use direct register access :)

Also added pyb.freq() function to get MCU clock frequencies.

4d7f4eb6a9 stmhal: Add ADC function to read data at a given frequency.
Reads ADC values into a bytearray (or similar) at a fixed rate.  Needs a
better name and improved API.  Also fix up DAC dma function (which also
needs a better name and API).

a12be917a4 stmhal: Add timer module; move servo PWM from TIM2 to TIM5.
As per issue #257, servo is better on TIM5 because TIM2 is connected to
more GPIO.
