Add general purpose timers and it sub-nodes into DT for stm32f4.
Define and enable pwm1 and pwm3 for stm32f469 discovery board

version 3:
- use "st,stm32-timer-trigger" in DT

version 2:
- use parameters to describe hardware capabilities
- do not use references for pwm and iio timer subnodes

If you're only commenting on a little piece of the patch, it's always
a good idea to trim the rest.

This is a much *better* format than before.

I still don't like the '&' syntax though.

Please keep "&" format to match with existing nodes.

Right.  I wasn't suggesting that he differs from the current format in
*this* set.  I am suggesting that we change the format in a subsequent
set though.

Why change? Looking at Linux ARM kernel patchwork, new DT board file 
contains this format. Did you already discuss with Arnd or Olof about it 
?

regards
Alex
