We load the Thunderbolt controller firmware to see if the controller is in native mode, as this changes the GUID. If the controller is asleep the firmware is not cached by the kernel and it can take more than 4 seconds to read out 504kB of firmware. We only need the first two 64-byte chunks, so only read what is required. This speeds up fwupd starting substantially, and also means we don't have to allocate a giant chunk of heap memory just to inspect one byte. Fixes: https://github.com/hughsie/fwupd/issues/848
