x86/boot/e820: Prefix the E820_* type names with "E820_TYPE_"

So there's a number of constants that start with "E820" but which
are not types - these create a confusing mixture when seen together
with 'enum e820_type' values:

	E820MAP
	E820NR
	E820_X_MAX
	E820MAX

To better differentiate the 'enum e820_type' values prefix them
with E820_TYPE_.

No change in functionality.
