Honghui Zhang 3828d60fd2 PCI: mediatek: Fixup MSI enablement logic by enabling MSI before clocks
Commit 43e6409db6 ("PCI: mediatek: Add MSI support for MT2712 and
MT7622") added MSI support but enabled MSI in the wrong place, at a step
in the probe sequence where clocks were not still enabled.

Fix this issue by calling mtk_pcie_enable_msi() in mtk_pcie_startup_port_v2()
since clocks are enabled when mtk_pcie_startup_port_v2() is called.

To avoid forward declaration of mtk_pcie_enable_msi(), move the
mtk_pcie_startup_port_v2() function definition in the file.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
