This change will allow to use different NVM file based
on WCN3991 BT SoC ID.Need to use different NVM file based on
fab location for WCN3991 BT SoC.

Hi Venkata,
I agree with Marcel that the version magic is confusing ...

Can we at least do the leN_to_cpu conversions in qca_read_soc_version()
as previously to make this less clunky?
And/or define a macro to extract 'soc_ver' to unclunkify this further.

The QCA_ prefix seems a bit verbose, given that this is a QCA driver and
WCN3991 uniquely identifies the chip. Having the prefix just needlessly
clutters conditions, I suggest to just call it SOC_ID_WCN3991.
