qcacmn: Add target information details to target_iflayer

Add a new target_psoc_info structure in the target if layer with the
following members

wmi_handle
target_type
target_version
target_revision

Also update the psoc data member tgt_if_handle to point to target_psoc_info
instead of pointing to WMI handle directly.

Updated all calls to psoc_get_tgt_if_handle to target_if_get_wmi_handle
which inturn calls psoc_get_tgt_if_handle and getting the tgt_if_handle
returns the WMI handle
