if_iwm - The iwm_prepare_card_hw() in iwm_attach() is only needed on 8K hw.

Browse Source 
* Doing the iwm_prepare_card_hw() call in iwm_attach() only on Family 8000
hardware matches the code in Linux iwlwifi.

* While there remove DEFAULT_MAX_TX_POWER definition which is unused, and
has a value different from IWL_DEFAULT_MAX_TX_POWER in iwlwifi.
