qcacmn: Add WAR for DBS mode phy0 band limitation

The limitation of having a single BDF for both DBS (2 radio)
and DBS_SBS (3 radio) capable board is leading to FW sending
 per-phy band-to-mac mapping as regulatory capability
as part of service_ext_ready. The boards which have the capability
of switching between DBS and DBS_SBS modes through init-time
(INI) file configuration are limited to 5G upper bound only
even in DBS mode becasue of the above constraint.

This WAR overwrites, in psoc-reg_cap, phy0 low or phy0 high frequency
depending on whether it is mapped to upper or lower 5G band by FW/hal-phy.
