x86: zboot: Move zimage definitions to the header file
In preparation for splitting the zboot-command code into a separate
file, move the definitions into the header file.
While we are here, mention when load_address and base_ptr are set up
and explain bzimage_addr better. Make cmdline const since it cannot be
changed.
