arch: x86_64: Update linux-loader crate
The linux-loader crate has been updated with a regnerated bootparams.rs which has changed the API slightly. Update to the latest linux-loader and adapt the code to reflect the changes: * e820_map is renamed to e820_table (and all similar variables updated) * e820entry is renamed to boot_e820_entry * The E820 type constants are not no longer included Signed-off-by: Rob Bradford <robert.bradford@intel.com>
