drivers: hwinfo: stm32: add support for STM32MP13

Browse source 
Adds the support for the STM32MP13 series to the existing STM32
Hardware Information driver.

Note that there is no  LL_GetUID_Word<x> functions for the STM32MP13
series. to allow to use HAL_GetUIDw<x> functions create macros to
fill the stm32_uid structure.
