stm32H7 spi LL driver read address of the Tx/Rx reg. for DMA

[FRASTM]

This patch adds the LL functions to get the address of SPI Tx/Rx reg. Unlike other series, the stm32H7 has two registers for Tx and Rx but no LL function is available to get their location when DMA requires it for its peripheral address reg.

Hi @FRASTM,

Thank you for this enhancement proposal. Would you mind signing the CLA so you pull-requests (this one and the others to come hopefully) could be processed? The procedure is simple. You can choose the "individual CLA" for more simplicity.

Thank you,
