Sticking to the existing wiphy should make error recovery much simpler and more reliable.

From: Alexey Brodkin <abrodkin@synopsys.com>
Subject: arc: enable unaligned access in kernel mode

This enables misaligned access handling even in kernel mode.
Some wireless drivers (ath9k-htc and mt7601u) use misaligned accesses
here and there and to cope with that without fixing stuff in the drivers
we're just gracefully handling it on ARC.
