qcacmn: construct shadow v2 config

In this change, hif requests hal construct the shadow register
configuration for all the necessary datapath rings.  Then hif
requests hal append the configuration for the srng rings used
by the host copy engine module.  When constructing the shadow
register configuration, the hal makes note to use the shadow
register addresses instead of the actual addresses.
