pit: setup voltage rails before system clocks

This moves the call to setup_power() before system_clock_init().
    This causes the PMIC to set up the voltage rails earlier so that
    the CPU clock can be set up at a faster rate (in the follow-up
    patch). After system clock init, we re-initialize the PMIC's I2C
    bus since the input clock rate will have changed.

pit: save setup_power() status and die later if needed

Since system clock and console initialization now happen after power
    setup, we cannot print error messages in setup_power(). This patch
    re-factors the code a little bit to save the status of setup_power()
    so that if we get an error during setup_power() we will wait until
    we can actually print something before dying.
