Introduce print_hex_dump_debug() that can be dynamically controlled, similar to
pr_debug.

You could just use "%*ph" specifier in pr_debug

Possibly true, but %*ph doesn't emit ascii nor
does it format a large block of data very well.

Maybe use of
	pr_debug("%*ph", len, buf)
vs
	print_hex_dump_bytes("prefix", DUMP_PREFIX_<STYLE>, buf, len)

could be described a bit in dynamic_debug_howto
or perhaps all of the various printk, dev_<level>,
<subsystem>_<level> styles and all the various
debugging options would be better described in a
new printk_howto
