[PATCH v2 0/4] reset: APIs to manage a list of resets

[Vivek Gautam]

Set of patches to support getting and de/asserting a list (array)
of reset controllers available with the device.

These patches address the comments received for the earlier
posted series [1,2].
The users can pass a list of reset controllers and the number of
resets available in the driver or the ones using device tree can
request the total number of reset controllers available in the
device node and pass the information to reset_control_array_* APIs
to _get(), _assert() and _deassert() the list of resets.

Changes since v1:
 - Addressed comment for error handling in of_reset_control_get_count()
 - Added patch to manage reset controller array.
 - Rebased dwc3-of-simple changes based on the new set of APIs
   for reset control array.
 - Added a patch for soc/tegra/pmc driver to use the new set of
   reset control array APIs.

-- Based on Torvald's master branch.
-- Tested usb on db820c target for dwc3-of-simple driver.
-- Build tested for tegra/pmc driver. Needs testing.
