e0f377fec0 stm32f4: use new rcc_clock_setup_pll()
Batch replaced to use new api.  User code doesn't need this, but
examples should be up to date, and this avoids deprecation warnings.

c03b580722 stm32: morse timer: remove WFI where not critical
__WFI is not standardized, though often provided.  As it's not a core
part of this example, drop it.

9af2b8c7fb stm32: morse timer: standardize example
Simplify, clarify and synchronize the two morse LED blinker examples.
Prepare for one day extracting the core as common morse example code.

d2abd471a5 stm32: timer: further clarify example commentary
The "timer" example is actually "the same" for both f1 and f4.  Do a
sanity sweep over the commentary, remove all vestiges that this was
cloned from a motor control example, and synchronize both examples.

Future work should extract the common portions "somewhere" but at least
make them consistent for now.

1260b16772 timer_reset -> rcc_periph_reset_pulse() replace
timer_reset wasn't fully implemented for all timers on all series, and
was simply a wrapper of the RST bits in the RCC registers anyway.

8924042d2a stm32f4: timer: correct misleading comments.
Code was correct, comment was badly imported.

976720c355 Updated libopencm3 to current master. Made all examples compile again.
Be specifically careful with the usb examples. There is likely some
breakage to be expected, not sure I updated all the drivers to the
correct types for the respective chips.

4de8d15303 [stm32f4-discovery] Using WFI instead of nop in the main loop.
WFI (Wait for Interrupt) tells the processor to suspend untill the next
interrupt is called. Better than burning away the cycles with nop.
