dt-bindings: spi: stm32: add st,stm32mp25-spi compatible

Add st,stm32mp25-spi compatible in dt-bindings.  STM32MP25 spi is similar
to the STM32H7 except for the following two points:
  - Burst should not be enabled with the new DMA used on STM32MP25.
  - STM32MP25 SPI8 has a limited feature set, it can only send words of
    8 or 16 bits and with a maximum words number of 1024.
