The transitions from low-power states to D0 and the other way around are unnecessarily tangled in pci_raw_set_power_state() which makes it rather hard to follow. Moreover, the only caller of pci_raw_set_power_state() passing PCI_D0 as its state argument is pci_power_up(), so the code carrying out transitions into D0 can be put directly into that function. Accordingly, move the code handling transitions from low-power states into D0 directly into pci_power_up() and rename the remaining part of pci_raw_set_power_state() to pci_set_low_power_state(), because it only handles transitions into low-power state now. While at it, fix up some white space, update some comments and modify messages printed by pci_power_up() and pci_set_low_power_state() to be less confusing (which is the only expected functional impact of this change).

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.
