Looks like the i2c timings in high-speed mode do not work properly to allow us to clear I2C_DISABLE bits for PRM_VOLTCTRL register and the device reboots if I2C_DISABLE bits are cleared. Let's configure the voltage controller i2c for low-speed mode as done in the Motorola Mapphone Android Linux kernel. This saves us about 7mW of power during retention compared to the high-speed values. Let's also change the low-speed warning to pr_info about relying on the bootloader configured low-speed values like we currently do.
