Make gpio32_stm32_configure use runtime PM API (so that it can be used
externally without further effort). The raw version of the function (no
PM put/get) has been introduced for internal use.

The PM runtime API (get/put) provides an inline implementation when not
built-in. Such implementation always returns 1, so it is safe to not
guard PM runtime calls and check for < 0.

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.

STM32G0/F0 SoCs allow to remap PA11/12 to PA9/10. Some boards
were manually configuring this remap. This patch centralizes this
functionality to the pinmux driver, allowing boards to enable the
remap directly in board dts file.

Remove APIs used in the pre-DT era. In case manual access is required,
`stm32_dt_pinctrl_configure` can still be used as a shortcut with data
initialized in the expected format.

Change the REMAP bits of the AFIO_MAPR of the stm32F1x soc
with local MACRO without changing the SWJ_CFG (write-only bits).
The serial wire JTAG configuration is taken from the Z_AFIO_REMAP
(value of the CONFIG_GPIO_STM32_SWJ_xxx))
and not read from the MAPR register.
It accesses to the MAPR register directly instead of LL functions.
Note that Remapping on the MAPR2 is not to change.

The equality check for remap was not being performed since the local
variable remap was assigned to the value being checked just before the
check. Some minor simplifications have been performed (fixed variable
types).

Move GPIO devices clock handling in stm32_pin_configure function
which is also used in stm32_setup_pins.
Additionally, add device usability check to be sure gpio driver
was initialized before being used by pinmux pseudo driver.
Last, going from the assumption that GPIO devices should be
initialized before being used by pinmux, then there is no need
to enable clock in case CONFIG_PM_DEVICE_RUNTIME=n.

There is a name clash when using G4 series LL TIM driver depending on
the inclusion order of the LL TIM and pinmux headers. If the LL headers
are included after pinmux is included, AF1 and AF2 definitions used by
pinmux clash with the AF1 and AF2 TIMx register names.
In order to solve this problem with minimum impact, the following has
been done:
1. Prefix the AFx and ANALOG definitions with STM32
2. In order to avoid changing all *-pinctrl.dtsi files, the STM32_PINMUX
macro contatenates STM32_ with the provided mode.

Add a common driver for pin control subsystem in STM32 MCU series. The
driver allows for selection of pin's function without the ability of pin
remapping.
The driver implements a pinmux driver API, with custom `func` and `pin`
encoding in API calls. The caller is expected to use STM32PIN() helper
macro for encoding port/pin numbers or using one of the provided
STM32_PIN_* defines.
The common driver requires SoC specific support to be implemented. The
SoC code must implement these calls: stm32_get_pin_config(),
stm32_get_port_clock(), stm32_pin_configure(). Consult pinmux_stm32.h
header for detailn on semantics of these calls.
The driver also requires board level integration. The call
stm32_board_get_pinconf() is expected to privide pin function
assignments for the target board.
Whenever an IO pin is being enabled, the driver will automatically
enable the clock for corresponding port. The driver does not implement
disabling of port's clock as this has potentially disruptive, as such
such operation should be done explicitly in the code.
The pin control module needs to be initialized before any other modules,
but after clock_control. For this reason, the driver is initialized by
default at PRIMARY level, with priority set to 2. The priority can be
changed through configuration.
