Aim of this change is to remove the need for the pinmux driver
on stm32f1 series to access the base address of the pinmux owner
device.
This is achieved by a modification in the device tree pin definition.
Instead of providing a generic information on type of the remap
(such as NO_REMAP, PARTIAL_REMAP, FULL_REMAP), the remap field
encodes all the information required to perform the remap register
configuration:
-Address of the targeted remap register in AFIO peripheral
-Position of the remap configuration in the remap register
-Mask used for the remap configuration encoding
-Value of the expected remap configuration.
All the possible remap configurations are encoded and predefined
in a new stm32f1-afio.h dt-bindings include.
To match this new configuration, all stm32f1 -pinctrl.dtsi should
be regenerated to use these new remap definitions.
