[Skiboot] [PATCH 1/2] hw/imc: move imc_init() towards end main_cpu_entry()

imc_init() checks for the 24x7 microcode state at boot to
check whether the microcode is in proper state (running or paused).
But in a larger system, loading of 24x7 microcode by OCC gets delayed.
Because of this, imc_init() removes imc devices from the device tree.
Moving imc_init() function towards end of the main_cpu_entry()
works around this.
