The nand driver normally while waiting for the device to become ready; this is normally fine, but xway_nand holds the ebu_lock spinlock, and this can cause lockups if other threads which use ebu_lock are interleaved. Fix this by waiting instead of polling. This mainly showed up as crashes in ath9k_pci_owl_loader (see https://github.com/openwrt/openwrt/issues/9829 ), but turning on spinlock debugging shows this happening in other places too. This doesn't seem to measurably impact boot time. Tested on bt_homehub-v5a with 5.10 and 5.15.
