x86/boot/e820: Clean up the E820_X_MAX definition
E820_X_MAX is defined in a somewhat messy fashion:
- there's a pretty pointless looking #ifndef __KERNEL__ define that
makes no sense in the non-UAPI header anymore,
- part of it is defined in api.h, which is not for type definitions,
- plus it's defined in two headers and the main explanation is in the
header where we don't have the real definition.
So move it into a single place in e820/types.h and get rid of the
!__KERNEL__ case altogether. Drop the smaller comment - the larger
one explains it just fine.
Note that the zeropage does not use E820_X_MAX, it uses the legacy
128 entries definition.
No change in functionality.
