x86/e820: Set System RAM type and descriptor
Change e820_reserve_resources() to set 'flags' and 'desc' from e820 types. Set E820_RESERVED_KERN and E820_RAM's (System RAM) io resource type to IORESOURCE_SYSTEM_RAM. Do the same for "Kernel data", "Kernel code", and "Kernel bss", which are child nodes of System RAM. I/O resource descriptor is set to 'desc' for entries that are (and will be) target ranges of walk_iomem_res() and region_intersects().
