    mips: Allow memory to be identity mapped in the TLB
    
    Introduce identity_map() function. It takes a memory range and
    identity maps it entirely in the TLB table, if possible. As a result
    the virtual and physical address ranges are the same.
    
    The function attempts to use as large of a page size as possible for
    each region in order to conserve TLB entries.
