Thomas Nixon 354ad1084a lantiq: nand: don't yield while holding spinlock 
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.
