Initialize CHIP_ANA_POWER to match power on defaults, which disables
ADC, DAC, and charge pumps.
In the process, remove references to the following register/bitfields
from the sgtl5000_set_power_regs routine:
        CHIP_ANA_POWER/LINREG_SIMPLE_POWERUP and
        CHIP_LINREG_CTRL/LINREG_VDD_MASK
And remove CHIP_ANA_POWER and CHIP_LINREG_CTRL from the set of default
registers so they don't get clobbered by sgtl5000_fill_defaults().
