Subject: mips: Use generic mult/shift factor calculation for clocks
Replace the MIPS functions of mult/shift factor calculation for clock
events and clock sources with inline functions which call the generic
functions. The minimum guaranteed conversion range is set to 4 seconds
which corresponds to the current MIPS implementation.
