[POWERPC] bootwrapper: Add fsl_get_immr() and 8xx/pq2 clock functions. fsl_get_immr() uses /soc/ranges to determine the immr. mpc885_get_clock() transforms a crystal frequency into a system frequency according to the PLL register settings. pq2_get_clocks() does the same as the above for the PowerQUICC II, except that it produces several different clocks. The mpc8xx/pq2 set_clocks() functions modify common properties in the device tree based on the given clock data. The mpc885/pq2 fixup_clocks() functions call get_clocks(), and pass the results to set_clocks().
