Merge tag 'u-boot-socfpga-next-20240415' of https://source.denx.de/u-boot/custodians/u-boot-socfpga

- Add option to reprogram FPGA every reboot, enable this as default in
  chameleonv3 defconfig.
- Fixes: Rename CONFIG_SPL_SOCFPGA_SEC_REG to CONFIG_SPL_SOCFPGA_DT_REG,
  so the driver can be built when CONFIG_SPL_SOCFPGA_DT_REG is set in
  defconfig.
