[PATCH] HID: Intel-thc-hid: Intel-quickspi: Correct device state after S4

From: Even Xu
Date: Mon Mar 03 2025 - 22:17:44 EST


During S4 retore flow, quickspi device was resetted by driver and state
was changed to RESETTED. It is needed to be change to ENABLED state
after S4 re-initialization finished, otherwise, device will run in wrong
state and HID input data will be dropped.
