x86/boot/e820: Introduce arch/x86/include/asm/e820/types.h
First baby steps towards saner e820 headers: create an exact copy of
arch/x86/include/uapi/asm/e820.h and use it from the asm/e820.h file.
No other changes - this is done to decouple the code from UAPI headers,
plus to make sure that subsequent modifications to the file can be more
clearly seen.
The plan is to keep the old UAPI header in place but the kernel won't
use it anymore - and after some time we'll try to remove it. (User-space
tools better have local copies of headers anyway, instead of relying
on kernel headers.)
This gives the kernel the freedom to reorganize the e820 code.
