Some of the QCA BTSoC ROME functions, are used for different versions
or different make of BTSoC's. Instead of duplicating the same functions
for new chip, updating names of the functions that are used for both
chip's to keep this generic and would help in future when we would have
new BT SoC.

Changes in v7:
* updated the all the functions of ROME to generic.
Changes in v6:
* initial patch
* updated names of functions that are used for both the chips to
keep this generic and would help in future when we would have
new BT SoC.
