qcacmn: Support hif window register and set init_phase for Kiwi

For Kiwi, if UMAC force wake is enabled, HIF window register
support is needed as well. currently hal_soc->init_phase just be
true for a very short periord, this lead to hif_force_wake_request
is called frequently when configure register during initialization,
this is not necessary as pld and device is not in power collapse
state during this period.

Enable HIF window register and increase init_phase true period
