Two convenience functions are added to operate on a range_entry:
- range_entry_update_tag() - update the entry's tag
- memranges_next_entry() - get the next entry after the one provide
These functions will be used by a follow on patch to the MTRR code
to allow hole punching in WB region when the default MTRR type is
UC.

The memrange infrastructure allows for keeping track of the
machine's physical address space. Each memory_range entry in
a memory_ranges structure can be tagged with an arbitrary value.
It supports merging and deleting ranges as well as filling in
holes in the address space with a particular tag.
The memrange infrastructure will serve as a shared implementation
for address tracking by the MTRR and coreboot mem table code.
