STM32: F1 GPIO: Enable AFIO clock

It is required to enable AFIO clock before using __HAL_AFIO_REMAP_xy
macros, which was missing here. Without clocks enable, the remap
actually doesn't occur. This would possibly cause some PIOs (part of
PB_3, PB_4, PA_13, PA_14, PA_15) to not behave as expected.

In most cases AFIO clock was enabled in stm_pin_SetAFPin function, so
that this bug was not visible. But there were few cases left were
stm_pin_DisconnectDebug would be called first. A typical case was
with GCC_ARM in case a DigitalInOut variable is declared as global.

STM32: common pinmap using LL layer to access registers

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.
