Some switch-cases were missing a fall through comment, so the compiler
may warn.  Fix that by adding the comments where needed.  In other
cases there was more text in the comment, which the compiler doesn't
recognize, so either remove the extra text or move it to a separate
comment line as appropriate.

There are several dumping flows in the driver in case of a fail
prior to operational.

In some cases we get 2 dumps while in others we get none.

Fix this by uniting the different flows.
Add a different dump type to driver triggered dumps in case we want
a dump but did not got assert, and make all dumping go through
iwl_fw_dbg_collect_desc to avoid multiple dumps.

There are two cases that can cause the alive flow to fail,
an assert or a timeout.
Currently we mask any incoming asserts when we wait for alive.

Solve this by differentiating between the two cases:
1. Let the regular error handling to handle a received assert
2. Do a dump collection in the case of a timeout

Prior to gen2 we allocate the paging memory via alloc_pages
which requires passing ownership on the memory between the
cpu and the device using dma_sync_single_for_cpu and
dma_sync_single_for_device.

Add missing dma_sync_single_for_device in iwl_dump_paging
after copying the memory.

since gen2, we allocate the paging memory using dma_alloc_coherent
which does not need passing ownership between the cpu and device.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf
("kbuild: do not drop -I without parameter").

I also removed one header search path in:

  drivers/net/wireless/broadcom/brcm80211/brcmutil/Makefile

I was able to compile without it.
