Bluetooth: hci_aml: validate firmware segment lengths
aml_download_firmware() reads two lengths from the firmware header and
uses them to build pointers before checking that the header and segment
data are present. A truncated or inconsistent firmware image can make
the driver read past firmware->data while constructing TCI commands.
Reject images shorter than the header and ensure that the ICCM and DCCM
ranges fit within the loaded firmware before downloading either segment.
