After the UFS device VCC is powered off, all the UFS device manufacturers require a minimum of 1ms of power-off time before VCC can be powered on again. This requirement has been verified with all the UFS device manufacturer's datasheets. Replace the hard coded 5ms delay with a variable with a default setting of 2ms to improve the system resume latency. The platform drivers can override this setting as needed. Signed-off-by: Bao D.

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.
