gpio: zynq: Check return value of pm_runtime_get_sync
Return value of "pm_runtime_get_sync" API was neither captured nor checked. Fixed it by capturing the return value and then checking for any warning. Addresses-Coverity: "check_return" Signed-off-by: Srinivas Neeli <srinivas.neeli@xilinx.com> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
