arm: stm32mp: bsec: Update OTP shadow registers in SPL
Currently the upper OTP (after 57) are shadowed in U-Boot proper,
when TFABOOT is not used.
This choice cause an issue when U-Boot is not executed after SPL,
so this BSEC initialization is moved in SPL and no more executed in U-Boot,
so it is still executed only one time.
After this patch this BSEC initialization is done in FSBL: SPL or TF-A.
To force this initialization in all the case, the probe of the BSEC
driver is forced in SPL in the arch st32mp function: spl_board_init().
Even if today BSEC driver is already probed in STM32MP15x clock driver
clk_stm32mp1.c because get_cpu_type() is called in
stm32mp1_get_max_opp_freq() function.
