staging: greybus: firmware: Convert sscanf calls to strtoul
Also convert the fw_update_type and fw_timeout variables to
unsigned and update the printf specifier to %u.
The FW_MGMT_IOC_SET_TIMEOUT_MS ioctl takes an unsigned int
and checkpatch was complaining about not checking the sscanf
return values.
