lib: sbi: Rename map_range/unmap_range functions

Browse Source 
*_map_range and *_unmap_range functions are required
in M-Mode to get the temporary access to S-Mode and U-Mode
regions. Thse functions only operate using the TYPE_MEMORY
memory protection mechanisms. Rename them to reflect the
actual usage of these functions and let generic map/unmap_range
names to implement generic functions
