[PATCH 2/6] Make num_var_ranges accessible outside MTRR code

[Thomas Schlichter]

Code outside MTRR will have to remember which MTRR entries are used for a
given purpose. Therefore it has to access num_var_ranges which holds the
value of the maximum count of MTRR entries available. So we make this value
accessible from outside the core MTRR code.
