There were still side effects, in particular on I2C master slave test,
when setting by default the Pin Speed for F1 family. So for F1 family,
let's do it only in case of Output which is the only case where this
actually applies on this family.
Up to now, speed was set for outputs and alternate, but this is
also valid for input configuration.
By default, let's configure high speed.
This is done firts, because speed for some families like F1 is mixed
with Input/Output mode settings, so can be later over-ridden if needed.
this first makes pinmap.c a common file
then rework it with several goals:
- avoid gpio / irq / pin management extra dependencies
- improve performances when switching between pin modes
This change is based on LL layer to access to registers level
instead of using HAL higher level API.
The family specific functions are implemented in pin_device.h
of each family. Mostly this is F1 family that is differnt
from other ones.
