Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

The move of the scan complete notification handling to the wiphy worker
introduced a race between scan complete notification and scan abort:
- The wiphy lock is held, e.g., for rfkill handling etc.
- Scan complete notification is received but not handled yet.
- Scan abort is triggered, and scan abort is sent to the FW. Once the
scan abort command is sent successfully, the flow synchronously waits
for the scan complete notification. However, as the scan complete
notification was already received but not processed yet, this hangs for
a second and continues leaving the scan status in an inconsistent
state.
- Once scan complete handling is started (when the wiphy lock is not held)
since the scan status is not an inconsistent state, a warning is issued
and the scan complete notification is not handled.
To fix this issue, switch back the scan complete notification to be
asynchronously handling, and only move the link selection logic to
a worker (which was the original reason for the move to use wiphy lock).
While at it, refactor some prints to improve debug data.

When there's an active link in a non-station vif, the station vif is
not allowed to enter EMLSR
Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule
an exit from EMLSR worker, but the worker cannot run before the
activation of the non-BSS link, as ieee80211_remain_on_channel already
holds the wiphy mutex.
Handle that by explicitly calling ieee80211_set_active_links()
to leave EMLSR, and then doing iwl_mvm_block_esr() only for
consistency and to avoid re-entering it before ready.
Note that a call to ieee80211_set_active_links requires to release the
mvm mutex, but that's ok since we still hold the wiphy lock. The only
thing that might race here is the ESR_MODE_NOTIF, so this changes its
handler to run under the wiphy lock.

The new link selection algorithm uses defaults values for BSS load if
the BSS Load element was not published by the AP.
For 6 GHz, that value is 0. So if the best link is 6 GHz, the EMLSR
grade to always be equal to the grade of the best link,
and then the best link grade is getting a bonus of 10 percent, meaning
that we will never activate EMLSR.
Change the logic to not give a bonus for the best link.

If the reason for exiting EMLSR was a blocking reason, wait for the
corresponding unblocking event:
- if there is an ongoing scan - do nothing. Link selection will be
triggered at the end of it.
- If more than 30 seconds passed since the exit, trigger MLO scan, which
will trigger link selection
- If less then 30 seconds passed since exit, reuse the latest link
selection result
If the reason for exiting EMLSR was an exit reason (IWL_MVM_EXIT_*),
schedule MLO scan in 30 seconds.

BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the
vif from using EMLSR with a different link pair. In addition, storing it
in mvmvif:disable_esr_reason requires extracting the BT Coex bit before
checking if EMLSR is blocked or not for a specific vif.
Therefore, change the BT Coex bit to be an exit reason and not a
blocker. On link selection, EMLSR mode will be re-calculated for the 2.4
GHz link instead of checking that bit.
While at it, move the relevant function declarations to the EMLSR
functions area in mvm.h
