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().
