The standard load_firmware() function is used on targets which use the "scramble -add" method for generating Rockbox binaries. While it tries to be a bit more generic and allows the CRC/data offsets to be placed anywhere in the file, there are no targets which actually need this flexibility, because they are all using plain old "scramble -add". So we can actually simplify load_firmware() and remove defines from the target headers. All the targets used CRC offset = 0 and data offset = 8, except for a few which I assume never supported ROLO or were never tested -- eg. samsungyh820: the CRC and data offsets cannot both be 0. The actual motivation for this is removing the calls to lseek(), which can help make bootloaders a tiny bit smaller, as lseek is typically not used anywhere else in bootloaders.
