Baochen Qiang 39564b475a wifi: ath11k: fix boot failure with one MSI vector 
Commit 5b32b6dd96 ("ath11k: Remove core PCI references from
PCI common code") breaks with one MSI vector because it moves
affinity setting after IRQ request, see below log:

[ 1417.278835] ath11k_pci 0000:02:00.0: failed to receive control response completion, polling..
[ 1418.302829] ath11k_pci 0000:02:00.0: Service connect timeout
[ 1418.302833] ath11k_pci 0000:02:00.0: failed to connect to HTT: -110
[ 1418.303669] ath11k_pci 0000:02:00.0: failed to start core: -110

The detail is, if do affinity request after IRQ activated,
which is done in request_irq(), kernel caches that request and
returns success directly. Later when a subsequent MHI interrupt is
fired, kernel will do the real affinity setting work, as a result,
changs the MSI vector. However at that time host has configured
old vector to hardware, so host never receives CE or DP interrupts.

Fix it by setting affinity before registering MHI controller
where host is, for the first time, doing IRQ request.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
