[PATCH v1] Bluetooth: qca: Refactor code on the basis of chipset names

[Vivek Sahu]

Whenever new chipset support is added to the driver code,
we ended up adding chipset name to the last of the switch case
arising code readability issue because of improper sorting of
the chipset names in various places of the code.

Refactor code such a way that new chipset can be added easily
in the code without compromising code readability.

If it was true, the file would have been less oragnized than it is now.
