arm: ls1021atwr: Add SD secure boot target

Add SD secure boot target for ls1021atwr.
Implement board 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.
