Fix a long standing VCPU reset sequence bug on BCM5906.
The VCPU(Virtual CPU) of BCM5906 is used to provide a mechanism to
control the bootcode execution and to pick up configuration data
stored inside the EEPROM.
The bootcode of BCM5906 will check the BGE_VCPU_STATUS_DRV_RESET
bit to decide which booting procedure to choose.
Data sheet indicates the VCPU of BCM5906 should set
BGE_VCPU_STATUS_DRV_RESET bit *before* VCPU reset or global reset.
