STM32WB HCI driver requires definition of 2 RAM regions to support
use of 3 shared memory sections: MAPPING_TABLE, MB_MEM1 and MB_MEM2.
In linker.ld, under conditions of HCI driver to be enabled,
define SRAM1 and SRAM2 based on input defined in stm32wb linker.
Then define the 3 sections MAPPING_TABLE, MB_MEM1 and MB_MEM

soc_register.h is available in most of stm32 series.
It is sometime empty or contains includes to flash_registers.h,
which is included directly with direct reference in flash driver.
soc_register.h is also included in stm32 clock drivers, but this
driver do not use direct reference to any register anymore.
Clean up these files.

In kernel_arch_init() we initialize the ARM core (interrupt
setup, fault init, etc.) so we can also move z_clearfaults()
in the same function and skip invoking it in the SoC init
functions.

ARM SysTick timer is implemented by default in ARMv7-M
and Mainline ARMv8-M processors, so we include the
corresponding Kconfig symbol in arch/arm/core/cortex-M/Kconfig
and remove the selections from the Cortex-M SOCs.

Add USART1 and LPUART1 nodes on stm32wb series.
Only these 2 ones are available for now on this series.

Add GPIO support to stm32wb series.
Only ABCDE and H ports are available for now on this series.
Accordingly, update series dtsi file.

Add support to stm32wb series in stm32 clock_control driver.
Ip is similar to stm32l4 one but AHB bus presacler is renamed
to "CPU1" and CPU2 and AHB4 prescalers should be defined.
