[PATCH AUTOSEL 4.4 25/77] macintosh/windfarm_smu_sat: Fix debug output

[Sasha Levin]

From: Benjamin Herrenschmidt <b...@kernel.crashing.org>

[ Upstream commit fc0c8b36d379a046525eacb9c3323ca635283757 ]

There's some antiquated debug output that's trying
to do a hand-made hexdump and turning into horrible
1-byte-per-line output these days.

Use print_hex_dump() instead
