Commit 5f4f954bba12 ("dt-bindings: bluetooth: bring the HW description
closer to reality for wcn6855") changed the vddrfa1p7-supply to 1p8
for whatever reason.

The schematics footprint for this chip definitely says 7 on the input
leg and the driver still expects 1p7. Bring it back.

The datasheet also describes "VDD17_RFA" and "RFA_VDD17" networks, so,
even if it has 1.8V, the net should be named 1p7.
