Yinghai Lu 3def3d6ddf x86: clean up e820_reserve_resources on 64-bit
e820_resource_resources could use insert_resource instead of request_resource
also move code_resource, data_resource, bss_resource, and crashk_res
out of e820_reserve_resources.

/*
* structures and definitions for the int 15, ax=e820 memory map
* scheme.
*
* In a nutshell, setup.S populates a scratch table in the
* empty_zero_block that contains a list of usable address/size
* duples. setup.c, this information is transferred into the e820map,
* and in init.c/numa.c, that new information is used to mark pages
* reserved or not.
