arm: stm32mp: move dbgmcu_init call when DT is ready
As the dbgmcu_init use the function bsec_dbgswenable which is based
on the DM and DT, its call can't be done before the spl is initialized
(driver model, DT and malloc) in board_init_f::spl_early_init().
This function call is moved later in spl_board_init().
