power: smb1355: Fix multiple I2C addr issue

SMB1355 is responding to both I2C addr of 0x0C and 0x0D due to setting
in slave ID register I2C_SS_DIG_PMIC_SID_REG.

To correct this issue such that SMB1355 only responds to 0x0C, SMB1355's
I2C_SS_DIG_PMIC_SID_REG must have only PMIC_SID0_BIT bit set through
secure write at the start.
