ASoC: Rename soc_enum.max field with items
The name "max" in struct soc_enum is rather confusing since it
actually takes the number of items. With "max", one might try to
assign (nitems - 1) value.
Rename the field to a more appropriate one, "items", which is also
used in struct snd_ctl_elem_info, too.
This patch also rewrites some code like "if (x > e->nitems - 1)" with
"if (x >= e->nitems)". Not only the latter improves the readability,
it also fixes a potential bug when e->items is zero.
