There is a chance that link enters hibern8 via auto-hibern8 scheme during the clock-gating flow. Clocks shall not be gated if link is still active otherwise host or device may hang. Fix this by returning error code to the caller __ufshcd_setup_clocks() to skip gating clocks there if link is not confirmed in hibern8 state yet. Also allow some waiting time for the hibern8 state transition.

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.
