[PATCH v2 1/7] mfd: max8997: Simplify getting of_device_id match data

[Krzysztof Kozlowski]

Use of_device_get_match_data() to make the code slightly smaller.  There
is also no need to wrap it in a check for CONFIG_OF, because dev.of_node
will be set only with OF support.

Changes since v1:
1. Remove check for CONFIG_OF
