linux-dey: ccimx95: add temporary patch to support early prototypes 

As the HWID support is not implemented yet, is needed to fill
the wireless information in the DT structure to have Wi-Fi and
Bluetooth working.
This is just a temporal patch for initial prototypes.

Subject: [PATCH] CC95: early prototypes: enable wireless interfaces
As the HWID is not completed yet, is needed to fill that info manually.
This is just temporal for the initial prototypes.
Additionally, in U-Boot, is needed to set the overlays as:
setenv overlays ccimx9_wifi.dtbo,ccimx9_bt.dtbo
