[PATCH v3 07/13] arm: stm32mp: bsec: Update OTP shadow registers in SPL

[Alexandru Gagniuc]

For TFABOOT and SPL_BUILD, stm32mp_bsec_probe() skipped updating the
OTP shadow registers. The idea is that we can't access BSEC from the
normal world. This is true with TFABOOT. However, in SPL, we are in
the secure world, so skipping probe is incorrect. In fact, SPL is not
even built when TFABOOT is selected.

Thus, do not skip this step for SPL_BUILD. Note that because SPL is
now doing this step, we no longer need to do it in u-boot. The new
logic is "let the FSBL do it", which is simpler.
