wifi: iwlwifi: Enable loading of reduce-power tables into several segments

Replace the field reduce_power_dram with a struct that holds data about
the reduced-power tables drams regions. Generalize load_payloads_segments()
to work for both pnvm tables and reduction power tables.
Make required adjustments in the data structures.

wifi: iwlwifi: Implement loading and setting of fragmented pnvm image

Save the pnvm payloads in several DRAM segments (not only in one as
used to). In addition, allocate a FW structure in DRAM that holds the
segments' addresses and forward its address to the FW. It's done when
FW has the capability to handle pnvm images this way (helps to process
large pnvm images).

Take the part that is copying the pnvm image into DRAM, out of the

wifi: iwlwifi: Generalize the parsing of the pnvm image

Generalize iwl_pnvm_parse(). This saves us from copying each payload
twice (first in the parsing and later when copying it to the dram).
Moreover, its more compatible for handling larger pnvm tables in
the future (in which payloads won't be concatenated).

The main changes are:

1. Take out the concatenating of the payloads from the parsing level
2. Start using iwl_pnvm_image structure that will hold pointers to
payloads that should be delivered to fw, their sizes and number.

iwlwifi: support loading the reduced power table from UEFI

This new feature allows OEMs to set a special reduced power table in a

power tables.

firmware. We do this as part of the PNVM loading flow.

In gen3, after firmware is alive, we no longer need the
firmware and image loader images, only the context info
itself and PRPH info/scratch need to remain.

Call iwl_pcie_ctxt_info_gen3_free() appropriately in the
alive callback (iwl_trans_pcie_gen2_fw_alive()) with a new
argument indicating whether it can free everything or only
partially.

The context info and PRPH scratch are also not needed after
PNVM load, but we don't have a good hook for freeing after
that, so keep them for now.

iwlwifi: pcie: support context information for 22560 devices

Context information structure was added to 22000 devices for
firmware self init.

In the next generation of devices the context information
changes significantly, and the original context information
is divided roughly to three data structures: context information gen3,
prph information and prph scratch.

In addition, the init flow changes so the firmware is loaded
by the IML, and so we must allocate the IML on the DRAM and
give the ROM the IML's address before kicking the firmware's
self init.
