x86/boot/e820: Move HIGH_MEMORY define to asm/e820/types.h
The HIGH_MEMORY define was in the API header, while it conceptually belongs to the other physical memory ranges in the e820/types.h header. Move it there - and also convert the 1MB address to hexa, so that it lines up more nicely with the other memory address values. No change in functionality.
