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.

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.
