3eb0694b97 stm32: Update HAL macro and constant names to use newer versions.
Newer versions of the HAL use names which are cleaner and more
self-consistent amongst the HAL itself.  This patch switches to use those
names in most places so it is easier to update the HAL in the future.

d29b709642 stm32/timer: Enable ARPE so that timer freq can be changed smoothly.
The timer prescaler is buffered by default, and this patch enables ARPE
which buffers the auto-reload register.  With both of these registers
buffered it's now possible to smoothly change the timer's frequency and
have a smoothly varying PWM output.

d7cd1d2027 stm32/timer: Make pyb.Timer() instances persistent.
Prior to this patch calling pyb.Timer(id) would always create a new timer
instance, even if there was an existing one.  This patch fixes this
behaviour to match other peripherals, like UART, such that constructing a
timer with just the id will retrieve any existing instances.

The patch also refactors the way timers are validated on construction to
simplify and reduce code size.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
