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.
