1. disable USB-gadget as this device has a UART available in HW
2. disable the fb detection (used for pbsplash), as I am not progressing
with getting HDMI working.

Since pmbootstrap!2426, pmbootstrap defaults to a `gpt` partition type,
the legacy u-boot on the cubox does not support `gpt`.
Therefor the deviceinfo was adjusted to return to `msdos` type partition
table.
Tested sucessfully on actual HW with new install
