x86/boot/e820: Create coherent API function names for E820 range operations
We have these three related functions:
extern void e820_add_region(u64 start, u64 size, int type);
extern u64 e820_update_range(u64 start, u64 size, unsigned old_type, unsigned new_type);
extern u64 e820_remove_range(u64 start, u64 size, unsigned old_type, int checktype);
But it's not clear from the naming that they are 3 operations based around the
same 'memory range' concept. Rename them to better signal this, and move
the prototypes next to each other:
extern void e820__range_add (u64 start, u64 size, int type);
extern u64 e820__range_update(u64 start, u64 size, unsigned old_type, unsigned new_type);
extern u64 e820__range_remove(u64 start, u64 size, unsigned old_type, int checktype);
Note that this improved organization of the functions shows another problem that was easy
to miss before: sometimes the E820 entry type is 'int', sometimes 'unsigned int' - but this
will be fixed in a separate patch.
No change in functionality.
