iwlwifi 9000 and a0000 series hw contains an extra dash in firmware
file name as seeen in modinfo output for kernel 4.14:

firmware:       iwlwifi-9260-th-b0-jf-b0--34.ucode

The 3168 series uses something in between,
so currently the driver uses incorrect offsets for it.

Integrated 9000 devices have a bug with shadow registers
value retention.
If driver writes RBD registers while MAC is asleep the
values are stored in shadow registers to be copied whenever
MAC wakes up.
However, in 9000 devices a MAC wakeup is not triggered
and when the bus powers down due to inactivity the shadow
values and dirty bits are lost.
Turn on the chicken-bits that cause MAC wakeup for RX-related
values as well when the device is in D0.
When the device is in low power mode turn the RX wakeup chicken
bits off since driver is idle and this W/A is not needed.
Remove previous W/A which was ineffective.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

_UCODE_API_OK was a intermediate version between MIN and
MAX. If a user had a firmware below _OK but above _MIN, the
driver would work but the user would get a warning in the
kernel log telling him to update his firmware.
This is not needed since most users won't look for these
messages in the kernel log if their wifi is working.

The 9000 series introduces several changes in the device
DMA operation.
As the device now supports multi-queue rx, several DMA channels
should be configured.
The flows of providing the device with the allocated RBDs now
changes as well - the device maintains a separate table of used
and free table.

The hardware may use the free table to feed RBDs to any queue.
This requires maintaing a shared table to map returned RBDs to
the original RXB - for that purpose the VID is introduced - an
internal identifier of the RB placed in the lower 12 bits and
returned by HW in the used data.

Another change is the support of 64 bit DMA address.
