Ruchika Gupta 70f9661ca9 arm: ls1043ardb: Add SD secure boot target
- Add SD secure boot target for ls1043ardb.
- Implement FSL_LSCH2 specific spl_board_init() to setup CAAM stream
  ID and corresponding stream ID in SMMU.
- Change the u-boot size defined by a macro for copying the main
  U-Boot by SPL to also include the u-boot Secure Boot header size as
  header is appended to u-boot image. So header will also be copied
  from SD to DDR.
- CONFIG_MAX_SPL_SIZE is limited to 90KB. SPL is copied to OCRAM
  (128K) where 32K are reserved for use by boot ROM and 6K for secure
  boto header.
- Error messages during SPL boot are limited to error code numbers
  instead of strings to reduce the size of SPL image.
