For QCA953x, this should be 0x180600b0 (if bit 7 is set then you have device mode).

GPIO13 is not connected according to ZBT.
not much i can do about that.

I'm not sure about default (internal) values.
Maybe keeping that I/O floating is the reason.

    You should first double check bootstrap configuration on your board.
    For host mode, GPIO13 should be pulled down.
