Reset controller updates for v7.1

Browse source 
* Rework the reset core to support firmware nodes, add more fine
   grained locking, and use guard() helpers.
 * Change the reset-gpio driver to use firmware nodes.
 * Add support for the Cix Sky1 SoC reset controller.
 * Add support for the RZ/G3E SoC to the reset-rzv2h-usb2phy driver and
   convert it to regmap. Prepare registering a VBUS mux controller.
 * Replace use of the deprecated register_restart_handler() function in
   the ath79, intel-gw, lpc18xx, ma35d1, npcm, and sunplus reset drivers.
 * Combine two allocations into one in the sti/reset-syscfg driver.
 * Fix the reset-rzg2l-usbphy-ctrl MODULE_AUTHOR email.
 * Fix the reset_control_rearm() kerneldoc comment.
 
 The last commit is a merge of reset-fixes-for-v7.0-2 into reset/next,
 to solve a merge conflict between commits a9b95ce36d ("reset: gpio: add a
 devlink between reset-gpio and its consumer") and fbffb8c7c7 ("reset: gpio:
 fix double free in reset_add_gpio_aux_device() error path").
