spi: tegra20-slink: Ensure SPI controller reset is deasserted
Commit 4782c0a5dd ("clk: tegra: Don't deassert reset on enabling
clocks") removed some legacy code for handling resets on Tegra from
within the Tegra clock code. This exposed an issue in the Tegra20 slink
driver where the SPI controller reset was not being deasserted as needed
during probe. This is causing the Tegra30 Cardhu platform to hang on
boot. Fix this by ensuring the SPI controller reset is deasserted during
probe.

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.
