Previously we were only checking the single-role firmware version.
Now add code to check for the firmware versions separately for each
firmware type.

The firmwares version string contain 5 integers. We used to consider
all the digits (except for the first one, which indicates the chip) as
linearly increasing version numbers. This is not correct, because
some of the integers indicate type of firmware (eg. single-role
vs. multi-role) or the internal project it was created for.
Besides, this varies a bit from chip to chip, so we need to make the
firmware version checks more flexible (eg. allow the lower driver to
ignore some of the integers). Additionally, we need to change the
code so that we only check for a linearly increasing number on the
fields where this actually makes sense.

The event mailbox in wl18xx has a different
(non-compatible) structure.
Create common functions in wlcore to handle the
events, and call them from the chip-specific
event mailbox parsers.
This way, each driver (wl12xx/wl18xx) extracts
the event mailbox by itself according to its
own structure, and then calls the common
wlcore functions to handle it.

Refuse to boot if the FW version is too old. The minimum version is set
per chip, with the option of setting it per PG in the future.
When boot fails because of an old FW, display a helpful message.

Don't spew errors when we can't find the NVS file in wlcore. Instead
fail the wl12xx boot HW op if the NVS isn't found.
Take this opportunity to remove some dead code from register_hw()
which looks for the NVS again needlessly.

The wl18xx firmware has more information in the static_data than
wl12xx. To be able to parse that in an abstracted way, this patch
adds a priv area to the static data struct and an operation that
allows the lower driver to parse it if necessary.

Different chip families have different firmware versions, so we need
to identify the firmware to enable quirks, reject the used version
etc. in the lower drivers. This commit turns the fw_ver_quirks
function into an identify_fw operation.

ELP is a very complicated process in the firmware. Due to its
complexity, in some early firmware revisions, the ELP feature is
disabled. To support this cases, this patch adds a quirk that
disables ELP mode.
When ELP is not supported, do not attempt to enter ELP when requested by
the driver.

Instead of checking the chip ID directly in the wlcore code to decide
whether to use the new or the old NVS format, we now use a quirk that
should be set by the low level driver to say that it needs to use the
old format.

The top registers initialization is very specific to the actual
hardware used, even the way in which we read from and write to the top
registers varies from chip to chip. This patch moves all top
registers initialization to wl12xx. Also add a boot op for the wlcore
module to call at the right time and a few callbacks with the common
called to be called from the lower drivers boot operations.
