meta-ampere: mtjade: bind smpro driver
Add script to bind smpro driver when the Host is available but it is not
bound before. This helps applications that use smpro driver works.
Tested:
1. Do A/C the system.
2. Turn ON the Host
3. Check if smpro nodes are available
# ls /sys/bus/i2c/drivers/smpro-core/
