Bluetooth: qca: Fix poor RF performance for WCN6855

[ Upstream commit a2fad248947d702ed3dcb52b8377c1a3ae201e44 ]

For WCN6855, board ID specific NVM needs to be downloaded once board ID
is available, but the default NVM is always downloaded currently.

The wrong NVM causes poor RF performance, and effects user experience
for several types of laptop with WCN6855 on the market.

Fix by downloading board ID specific NVM if board ID is available.
