[Bala]: This part we need to rethink to having to optimize.
ROME use: rampatch<>.tlv
WCN399x: uses cr<>.tlv
QCA6390: uses ht
tomorrow if some new chipset comes, it uses different name again a we
need to handle this part.
i would suggest add this prefix to "qca_bluetooth_of_match"
which can be passed as argument
