power: ab8500_charger: Remove deprecated create_singlethread_workqueue
alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces deprecated create_singlethread_workqueue(). This is the identity conversion. The workqueue "charger_wq" is used for the IRQs and checking HW state of the charger. It has been identity converted. It has multiple work items viz usb_charger_attached_work, kick_wd_work, check_vbat_work, check_hw_failure_work, usb_charger_attached_work, ac_work, ac_charger_attached_work, attach_work and check_usbchgnotok_work, which require execution ordering. Hence, a dedicated ordered workqueue has been used here. The WQ_MEM_RECLAIM flag has also been set to ensure forward progress under memory pressure.
