Some NIC comes with more than the 4 NVM (non volative
memory) sections described in the nvm_to_read array.
These NICs usually get their NVM from an external file
fetched from userland during init.
We already parsed the file, but sent to the NIC only 4 NVM
sections whereas there could be more sections in the file.
Fix this.

In case of invalid section_id, the function returns after
it aleready allocated memory. Fixed by change the order of actions.

This allows to see the content of the NVM the driver reads.
Note that the output is in binary, and requires some
external user space tool to display the data properly.

Section size limitation to 6000 is incorrect.
NVM file need to support bigger sections in order
to support PAPD tables.

Some NICs aren't allowed to be powered up at driver load time.
Fix it, and move the external NVM loading from driver load time to
driver up time (parsing the external nvm file remains at driver load time).

I forgot to take them from TLV and took them from the NVM
instead.

If RF-kill is asserted while a device is initialized, the
firmware INIT image can now be run to retrieve the NVM
data and register to mac80211 properly. Previously, the
initialisation would fail in this scenario and the driver
wouldn't register with mac80211 at all, making the device
unusable.

Some newer devices will be integrated into the platform more
deeply and will not have embedded NVM (EEPROM/OTP). To support
such devices the NVM data must be provided by the platform,
allow loading the data via request_firmware() and then send it
to the device as needed.

These messages aren't really useful, suppress them unless

If NVM parsing fails and returns NULL, we continue in
the code flow and eventually crash accessing the NULL
pointer. Return an error from iwl_nvm_init() if the
parsing failed.

Newer firmware revisions have a completely new
firmware API. This is the new driver for this
new API.

I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.
