iwl_phy_db_set_section() is get called only from atomic

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.

The firwmare file can come with data that is relevant for paging. This
data is availablet to the firmware upon request, but it stored in the
host's memory. During the firmware init flow, the driver configures the
firmware so that the firwmare knows where is the data.
When paging is used, the variable paging_mem_size is the number of bytes
that are available through paging. This variable is not zeror-ed if the
driver fails to configure the paging in the firmware, but the memory is
freed which is inconsistent.
This inconsistency led to a NULL pointer dereference in the code that
collects the debug data.
Fix this by zero-ing the paging_mem_size variable and NULLify the
relevant pointers, so that the code that collects the debug data will
know that the paging data is not available.

Improve current RSS configuration:
* Use netdev_rss_key instead of keeping a local copy.
* Configure also UDP hashing to have UDP traffic spread across queues.
* Do not direct RSS traffic to our fallback queue.

In case of FW error, support dumping the UMAC internal txfifos.
To do so, support version 2 of shared memory cfg command, which
contains the sizes of the internal txfifos, and move the command
to the system group.

Paging contains 3 sections in the fw. The first for the paging separator,
The second for the CSS block, the third with the paging data.
Currently if the driver finds the paging separator, and there is only
section left (CSS), once reading the CSS section, the driver will
attempt to read the paging data and will go out of the arrays bounds.
Make sure that the FW image contains the right amount of sections for
paging.

Currently the driver has 2 buffers for paging:
1. paging db - this contains all of the pages that were in the FW
image, that the driver stores for the FW. This is allocated for each
block separately (not contiguous).
2. download buffer - we need to provide this empty buffer for the
iwl_sdio_load_fw_chunk function to copy the requested pages to the shared
memory. This is one big buffer of contiguous memory whose size is the
size of all the blocks that the fw paging section can contain.
This download buffer size is too big, and causes the allocation to fail
sometimes. Since the driver allocates memory for each block separately,
it is not possible for the FW to request all of the pages in one request
(the FW gives an address and size, so blocks need to be contiguous for
this to happen), therefore the FW is limited to request only one block.
Decrease the size of the paging download buffer to be the size of a
paging block.

Leaving ucode_loaded to true after stop_device() has been called
is a recipe for problems. Flows that are not sync'ed with the
driver life cycle (like debugfs hooks and thermal hooks) must
check that the firmware is loaded before they interact with it.
Therefore we need to keep this variable updated with the real
status of the firmware.

Till today, the ucode consisted of two d0 images - regular,
in which the usniffer wasn't enabled, and usniffer, in which the
usniffer logs were enabled.
Lately, the two images were unified, so there is only one d0 image,
in which the usniffer logs are enabled.
Add new TLV capability for supporting the consolidated images
(set 2, bit 13).

The initialization and copying of the RSS secret key
should not use ARRAY_SIZE as we need to initialize a
dword array, and not a byte array.
Fix also the hook maximum write size to allow writing
a longer table - up to full indirection table size.

9000 series supports multi-queue rx. The hardware needs
to be configured with the hash functions to perform and
indirection table that maps hash results to the relevant
CPUs\queues.
Support this configuration.
Add debugfs hook to configure the indirection table in
order to enable performance analysis. The configuration
is stateless, receives a partial or full pattern and sends
the command to the firmware.

If we don't reset the scan type when the firmware is
started, we will think the firmware is still configured
after the interface has been brought down. When we will
bring it up again, we will not configure the scan type
in firmware and it will crash with the following assert:
0x0000100A | ADVANCED_SYSASSERT
