However, the Dahlia carrier board supports disabling the sleep-moci when the system is suspended to power down peripherals that support it. This reduces overall power consumption. This commit adds support for this feature by disabling the reg_force_sleep_moci regulator and adding a new regulator for the USB hub that can be turned off when the system is suspended.
