Subject: [PATCH v2] mfd: max8997: Simplify probe() and drop max8997_i2c_get_driver_data()

Simplify probe() by using i2c_get_match_data() instead of
max8997_i2c_get_driver_data() for retrieving match data from
OF/ID tables.

Note:
 This patch is only compile tested.

v1->v2:
 * Used uintptr_t for enum casting.
