x86/boot/e820: Clean up the E820 table size define names
We've got a number of defines related to the E820 table and its size:
E820MAP
E820NR
E820_X_MAX
E820MAX
The first two denote byte offsets into the zeropage (struct boot_params),
and can are not used in the kernel and can be removed.
The E820_*_MAX values have an inconsistent structure and it's unclear in any
case what they mean. 'X' presuably goes for extended - but it's not very
expressive altogether.
Change these over to:
E820_MAX_ENTRIES_ZEROPAGE
E820_MAX_ENTRIES
... which are self-explanatory names.
No change in functionality.
