This was inherited from iwlwifi, which drives devices supported by both
iwn(4) and iwm(4) in FreeBSD. In iwm(4) _mvm is meaningless, so remove
it. OpenBSD made the same change a long time ago. No functional change
intended.

* This fixes cases where the group id of wide commands got lost, e.g. this
happened to the IWM_SCAN_ABORT_UMAC command.

This might improve throughput slightly when far from the accesspoint,
apparently by allowing the firmware to listen on either of the two
antennas (if there are two, i.e. on 7260/7265/8260), whichever has
a better reception.

* Add iwm_pcie_set_cmd_in_flight() and iwm_pcie_clear_cmd_in_flight()
helper methods.
* Use ring->queued tracking in the command queue to set/clear the
cmd_hold_nic_awake bit at the right points.

* This fixes the phy_cfg field sent in the iwm_send_phy_cfg_cmd()
command, which wasn't taking into account the valid_rx_ant and
valid_tx_ant masks from nvm_data before.
Tested:
* 7260, STA mode, 2G and 5G
Obtained from: DragonflyBSD commit cbb82693c18fd71b4eb86855b82d03995f352d65
* sc->sc_nvm becomes sc->nvm_data and is now a pointer instead of an
inlined struct.
* Add sc->eeprom_size and sc->nvm_hw_section_num configuration values to
struct iwm_softc.
* For now continue to avoid negative error return-values, and use pointer
variables for some return values, as before.
* Continue to omit LAR (location aware regulatory) related code as well.
Tested:
* Intel 7260, STA mode (2GHz)

We also need to consider the size of large firmware commands in iwm_alloc_tx_ring(),
in the dma tag creation, when qid == IWM_MVM_CMD_QUEUE. The old code apparently
only allocated a 2KB (MCLBYTES) sized buffer when it actually expected 4KB.

There are still several bugs, but I've been using it for a while now.
Thanks to all the testers and to Adrian for his help with this
driver.
This driver isn't connected to the build yet, but it will be soon.
There's no MFC planned because the driver isn't very stable yet.
