[iwm] Remove a couple of unneeded IWM_UCODE_TLV_FLAGS_* flags.

Browse Source 
* All the supported firmwares have these flags set.

* This removes the following flags:
  IWM_UCODE_TLV_FLAGS_PM_CMD_SUPPORT,
  IWM_UCODE_TLV_FLAGS_NEWBT_COEX,
  IWM_UCODE_TLV_FLAGS_BF_UPDATED,
  IWM_UCODE_TLV_FLAGS_D3_CONTINUITY_API,
  IWM_UCODE_TLV_FLAGS_STA_KEY_CMD,
  IWM_UCODE_TLV_FLAGS_DEVICE_PS_CMD,
  IWM_UCODE_TLV_FLAGS_SCHED_SCAN,
  IWM_UCODE_TLV_FLAGS_RX_ENERGY_API,
  IWM_UCODE_TLV_FLAGS_TIME_EVENT_API_V2

* Also remove definitions and code for dealing with the v1 time-event api.

* Remove unneeded calc_rssi() function.
