common: constrain object mapper call

Fix this call site where we are fetching configuration to call
'GetSubTree' with our configuration interfaces as argument.

resolves [1]

Tested: With SPI device code updater. Configuration is fetched as
expected.

```
<7> [config] looking for dbus interface xyz.openbmc_project.Configuration.BIOS
```

```
busctl call xyz.openbmc_project.ObjectMapper /xyz/openbmc_project/object_mapper xyz.openbmc_project.ObjectMapper GetSubTree sias /xyz/openbmc_project/ 0 1 xyz.openbmc_project.Configuration.BIOS
a{sa{sas}} 1 "/xyz/openbmc_project/inventory/system/board/chassis/HostSPIFlash" 1 "xyz.openbmc_project.EntityManager" 1 "xyz.openbmc_project.Configuration.BIOS"
```
