When device cable is disconnected core receives suspend interrupt and enters hibernation. After entering into hibernation GPWRDN_RST_DET and GPWRDN_STS_CHGINT interrupts are asserted. Allowed exit from gadget hibernation from GPWRDN_RST_DET by checking only linestate. Changed the return type of "dwc2_handle_gpwrdn_intr()" function from void to int because exit from hibernation functions have a return value.

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.
