The Voltage Regulator Mode Controller contains one read/write register, the Voltage Regula-
tor Mode Register. Its offset is 0x60 with respect to the System Controller offset.
This register controls the Voltage Regulator Mode. Setting PSTDBY (bit 0) puts the Voltage
Regulator in Standby Mode or Low-power Mode. On reset, the PSTDBY is reset, so as to
wake up the Voltage Regulator in Normal Mode.
