In (first) breaking and (then) fixing the rkspi tool, I realised that the calculation of the required padding (for the header-size and the 2K-in-every-4K SPI layout) was not as self-explainatory as it could have been. This change rewrites the code (using new, common functions in rkcommon.c) and adds verbose in-line comments to ensure that we won't fall into the same pit in the future...
Tested on the RK3399 (with has a boot0-style payload) with SD/MMC and SPI.
