rockchip: Fix rkimage format for SPL boot over USB
The 'rkimage' format used for booting rockchip boards over USB seems to have been broken since commit7bf274b9ca
("rockchip: mkimage: use imagename to select spl hdr & spl size"). That commit adds an offset of RK_SPL_HDR_START(=2048) to the location the 'RKxx' header is written at. However the bootrom expects this header to be the first four bytes of the image, not at offset 2048. This appears to have been a copy paste error since the 'rksd' and 'rkspi' image types do require this offset. Furthermore commit111bcc4fb6
("rockchip: mkimage: pad the header to 8-bytes (using a 'nop') for RK3399"), commit3d54eabcaf
("rockchip: spl: RK3399: use boot0 hook to create space for SPL magic") and commit3082775692
("rockchip: mkimage: update rkimage to support pre-padded payloads") changed the way the space for the 'RKxx' header is allocated and written to the image without adjusting 'rkimage'. This commit fixes those mistakes and makes it possible to load u-boot SPL over USB once more.
