Shawn Lin 0835fbe0d1 PCI: dw-rockchip: Remove PCIE_L0S_ENTRY check from rockchip_pcie_link_up()
commit 7d9b5d6115 upstream.

rockchip_pcie_link_up() currently has two issues:
1. Value 0x11 of PCIE_L0S_ENTRY corresponds to L0 state, not L0S. So the
naming is wrong from the very beginning.
2. Checking for value 0x11 treats other states like L0S and L1 as link
down, which is wrong.

Hence, remove the PCIE_L0S_ENTRY check and also its definition. This allows
adding ASPM support in the successive commits.

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 reStructuredText 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.
